Tomorrow we will be viewing bodies that have undergone a procedure known as Plastination. I would like to research what this procedure is, the chemicals involved, and how it is done. Also, who is Gunther von Hagens'? How did he come about with the idea of plastination? What jobs did he have in life
Plastination is a procedure through which certain waters and fats in the body undergo that hardens them and replaces them with different types of plastics. There are four steps in the standard process of plastination: fixation, dehydration, forced impregnation in a vacuum, and hardening. Water and lipid tissues are replaced by curable polymers. Curable polymers used by plastination include silicone, epoxy and polyester-copolymer. Gunther von Hagens Anatomist, inventor of Plastination, and creator of BODY WORLDS—The Original Exhibitions of Real Human Bodies—von Hagens (christened Gunther Gerhard Liebchen) was born in 1945, in Alt-Skalden, Posen, Poland—then part of Germany. To escape the imminent and eventual Russian occupation of their homeland, his parents placed the five-day-old infant in a laundry basket and began a six-month trek west by horse wagon. The family lived briefly in Berlin and its vicinity, before finally settling in Greiz, a small town where von Hagens remained until the age of 19.
ReplyDeletePlastination is a science-based process in which the human anatomy is preserved. During a vacuum procedure, organic specimens are thoroughly spread with a reactive polymer developed specifically for this method. The category of polymer used determines the mechanical (flexible or hard) and optical (transparent or opaque) qualities of the protected specimen. Gunther von Hagens is a German anatomist. "The purpose of Plastination from its very inception was a scientific one; I wanted to improve anatomy for medical students at the University of Heidelberg, where I was a researcher teaching anatomy. The specimens of that time, embedded in polymer, like a cherry frozen deep inside an ice cube, were not good enough, or so I felt at that time." said Hagens in a recent interview about Body Worlds. Hagens was a teacher and also a research assistant at the Institute of Pathology and Anatomy at the University of Heidelberg before coming up with plastination and his current job as creator of the new exhibit of the human body and the brain called "Body Worlds".
ReplyDeletePlastination is a scientific process used to preserve the anatomy of a human or animal. Acetone, formaldehyde solution, liquid polymer, such as silicone rubber, polyester or epoxy resin. First, the body is embalmed in a formaldehyde solution, then the body is put into a bath of acetone Under freezing conditions, the acetone draws out all the water and replaces it inside the cells. In the third step, the specimen is then placed in a bath of liquid polymer, such as silicone rubber, polyester or epoxy resin. By creating a vacuum, the acetone is made to boil at a low temperature. As the acetone vaporizes and leaves the cells, it draws the liquid polymer in behind it, leaving a cell filled with liquid plastic. The plastic must then be cured with gas, heat, or ultraviolet light, in order to harden it. Gunther Von Hagens is a controversial German anatomist who invented the technique for preserving biological tissue specimens called plastination. He got the idea when he was working in his butcher shop and thought to himself that it should be possible to infuse a kidney slice with plastic by saturating it with acetone and placing it under a vacuum; the vacuum would then extract the acetone in the form of bubbles, just as it had extracted air before. He was a research assistant at the Institute of Pathology and Anatomy at the University of Heidelberg.
ReplyDeletePlastination is used in anatomy to preserve body parts. The water and fat in the body is replaced by plastic. Because of this, the bodies don't smell or decay, and most of the body is identical to the original sample. There are four steps in this process: fixation, dehydration, forced impregnation in a vacuum, and hardening.
ReplyDeleteGunther von Hagens is a german anatomist, born January 10th, 1945. He was a hemophiliac as a child, and spent six months in a hospital. This stimulated his interest in medical science. He continued his medical studies in Lübeck, and received a doctorate in 1975 from the University of Heidelberg. There he would work at the Institutes of Anatomy and Pathology as a lecturer for twenty two years.
Plastination is a procedure that is used to preserve body parts or entire bodies. Certain types of plastics replace the fat and water in the body, making it so the parts can be touched. The body also will not rot. There are four steps to plastination: fixation, dehydration, impregnation, and hardening. Fixation is the embalming of the body so it won't decay. During dehydration, the body is placed in acetone, which gets rid of the water. Impregnation is when the body is placed in liquid polymer, causing the acetone to vaporize and leave the cells. The final step is hardening, which is hardening the body using gas, heat, or ultraviolet light. Gunther von Hagens is the man who invented plastination. He got his inspiration from his love of medical sciences. His different occupations are anatomist and lecturer.
ReplyDeleteThe four main steps in Plastination are fixation, dehydration, forced impregnation in a vacuum, and hardening. The chemicals involved are formalin, acetone, and a reactive polymer. Gunther von Hagens' is a German anatomist. He invented the plastination technique. Hagen was a haemophiliac as a child and being in the hospital a lot is what sparked his interest in medical science. This eventually led him to study anatomy, where he learned how to preserve bodies. Throughout his life, Hagen has had many jobs such as an intern, lecturer, visiting professor, director of the Plastination Reasearch Center, owner of a private company, and anatomist.
ReplyDeletePlastination is a process where tissue and organs, or a whole body, are preserved. The process includes taking away all the natural water and fats that cause the body to decay and replace them with polymers. But, water cannot be directly replace with the polymer, so right when they are in the "fluidexchange" step, they initially replace the natural substances with acetone, a "solvent that readily evaporates". Then, they replace the acetone with the "reactive polymer"
ReplyDeleteGunther von Hagens is the scientist that discovered plastination. When he was a child, he had a rare bleeding disorder and was once hospitalized for a long time, and the doctors made a big impression on, as did the launch of the Sputnik. He was arrested at the age of 23 for trying to escape from Germany. After his imprisonment, he returned to medical school and graduated. He then joined the Department of Anesthesiology and Emergency Medicine at Heidelberg University, but soon left because he thought it was too boring. In 1975, while serving as a resident and lecturer at the Institute of Pathology and Anatomy, von Hagens invented plastination. He didn't get why specimens had to be preserved in huge blocks of plastic, and you couldn't hold them. That is what sparked the idea plastination.
Plastination is a technique used in anatomy to preserve bodies or body parts.The four steps to get to the final product that we will be viewing at body worlds are fixation, dehydration, forced impregnation in a vacuum, and hardening. Water and lipid tissues are replaced by curable polymers. Curable polymers used by plastination include silicone, epoxy and polyester-copolymer. The step of hardening is when the bodies get posed for whatever they would be doing from riding a skateboard or just sitting. During this process is when the poses stay put through hardening the bodies. Gunther von Hagens is an anatomist, inventor of Plastination, and creator of Body Worlds. He thought of the idea when he was at a butcher's shop, In its essentials, plastination involved the injection of polymers—plastics—into a cadaver that had been frozen and then dehydrated. The beginning idea was just for the benefit of medical schools so that they would have a sure supply of human organs for instructional purposes. In 1993, he could plastinate the entire human body, opening this up for display to the world. In 1975 he received a doctorate from the University of Heidelberg, he worked at the Institutes of Anatomy and Pathology as a lecturer for twenty two years. Now he works in a concealed lab creating more displays for existing and future body worlds.
ReplyDeletePlastination:
ReplyDeleteThe procedure is embalming bodies in silicone with acetone.
The procedure is done with three successive silicone baths as a means of preventing a single bath (along with its contents) from curing too quickly, after curing the specimen in a laboratory kiln, the process was finished.
Acetone is one of the main chemicals that replaces the water in the tissues. Other chemicals are not disclosed.
Gunther Von Hagens:
Gunther was born in Poland and from there was placed in a laundry basket for a six month trek to Berlin, where his family lived for a little while before making it's final residence in Greiz. He stayed there until the age of 19. As a child he was diagnosed with a bleeding disorder and was hospitalized for many months at a time. At six, he almost died and practically lived in the ICU. He entered medical school in 1965. At 23, Von Hagens was incarcerated.
Jobs: Resident at a hospital on Heligoland. Lecturer at the Institute of Pathology and Anatomy. His third job was working at the Department of Anesthesiology and Emergency Medicine at Heidelberg University.
He came about the idea of plastination while working as a research assistant.
Plastination is the process in which you preserve bodies and body parts. The water and the fat in the body are then taken out and replaced by special plastics which will help with the preservation of the body. During this process they use the chemicals called reactive polymers. This process is done by first taking out the fat and water from the tissues and putting in the plastic replacements. This is because they want to take away what the bacteria needs to survive. Once the bacteria dies, they vacuum out the acetone from the body. After a while the body can be examined without the body decaying.
ReplyDeleteGunther von Hagens was a German anatomist who had created a technique to preserve bodies. This process was called plastination. Since he is most known for his plastination process, he had been a guest professor at the New York University College of Dentistry, Dalian, China, and he also directs the State Medical Academy in Bishkek, Kyrgyzstan. Gunther von Hagens applied for a German patent, when he proposed the idea of preserving animal and vegetable tissues permanently by synthetic resin impregnation
There are four main steps in the process of plastination: fixation, dehydration, forced impregnation in a vacuum, and hardening.
ReplyDeleteFirst, water and lipid tissue are removed. They are then replaced with curable polymers. They then embalm the body, typically with formaldehyde to prevent it from decomposing. After the body is embalmed, it is dissected and placed into freezing cold acetone. At freezing conditions, acetone pulls all of the water out of cells. The body is then dipped in a liquid polymer like silicone rubber, polyester or epoxy resin. The body is then put in a vacuum causing the acetone to evaporate and the polymer to move into the cell. After the polymer is hardened with gas, heat, or ultraviolet light, you end up with a body hardened and filled with plastic.
His jobs include intern, lecturer, visiting professor, director of the Plastination Reasearch Center, owner of a private company, anatomist, and creator of Body Worlds.
"I developed the Plastination technique at the University of Heidelberg’s Institute of Anatomy in 1977, patented it between 1977 and 1982, and have been continually improving the process ever since." Gunther van Hagen said about his idea. Plastination is the is a process using fixation, dehydration, and forced impregnation to preserve a body. The process of plastination is:
ReplyDelete1.) Halting decay by pumping formalin into the body. Then the skin and fatty tissues are removed.
2.) The body's water and soluble fats are dissolved in an solvent bath (usually acetone)
3.) Forced impregnation is done by soaking the body in a reactive polymer solution and then putting it in a vacuum chamber.
4.) The body is positioned as desired
5.) The specimen is hardened with light, gas, or heat
Gunther van Hagen was a very interesting man. He was an anatomist, creator of body worlds, and the inventor of plastination. He was held in a East German prison for 2 years from trying to escape from Germany. He was diagnosed as a child with a rare bleeding disease. During his life he was an intern, lecturer, visiting professor, director of the Plastination Reasearch Center, owner of a private company, and anatomist.
The steps to Plastination are as follows:
ReplyDelete1.) Fix the specimen with a fluid called formalin which is an embalming fluid.
2.) The specimen is then washed in cool running water for one to three days to clear it of any lipids.
3.) Next, submerge the specimen in acetone to dehydrate it. Depending on the size of the specimen, it may take up to three washes to completely dehydrate the body. To complete this step, the specimen must have 1% water or less.
4.) Place the specimen in a polymer/crosslinker bath for a full 24 hours. Then put the specimen in a vacuum chamber and once there is full vacuum pressure, the acetone is exchanged with the polymer and it will begin bubbling. When the bubbling ceases, the exchange is complete.
5.) Remove the specimen from the bath and let it drain, wiping off any excess polymer/crosslinker. Place a thin layer of catalyst on the specimen and let is cure.
Gunther con Hagens was a research assistant at the Institute of Pathology and Anatomy at the University of Heidelberg and also a teacher. The idea of Plastination came to him in a butcher shop. He became interested in the human body when he was in the hospital watching all of the doctors and nurses.
What is Plastination?
ReplyDelete~Plastination is when the things inside the body of a dead person is hardened and the dehydration of the body. Water and lipids are replaced by curable polymers. Makes the body into a 'plastic' hence the term 'plastination'.
What chemicals are involved?
~Chemicals such as formaldehyde, alcohol, and glycerin are used in plastination.
How is Plastinaiton done?
~All of the fat in the body is replaced with certain plastics. This process takes up to about a month.
Who is Gunther von Hagens'?
~ Gunther von Hagens is a German anatomist who invented plastination. He invented this technique in 1977. He now owns a plastination center and also developed Body Worlds.

Gunther von Hagens was a german anatomist who invented the technique for preserving biological tissue specimens called plastination. He had a job as a research assistant at the Institute of Pathology and Anatomy at the University of Heidelberg. He came up with the idea when viewing bodies being preserved by being encased in a block of plastic. He questioned "...why the plastic was poured and then cured around the specimens rather than pushed into the cells, which would stabilize the specimens from within and literally allow you to grasp it."
ReplyDeletePlastination makes it possible to preserve individual tissues and organs that have been removed from the body of the deceased as well as the entire body itself.
Steps to Plastinate:
1. Embalming and Anatomical Dissection
2. Removal of Body Fat and Water
3. Forced Impregnation
4. Positioning
Chemicals Involved:
Acetone, formaldehyde solution, liquid polymer, such as silicone rubber, polyester or epoxy resin.
Plastination is used in anatomy to preserve bodies and body parts. The water and fat are replaced with a certain plastic. The plastic is special because it can be touched, it doesn't smell, and it won't decay. There are four steps involved in plastination are: fixation, dehydration, forced impregnation, and hardening. Gunther von Hagens was the inventor of plastination. He had many donors that trusted him to preserve their dead bodies with his procedure and dissection. He was a teacher carrying on the tradition of Renaissance anatomists, and a research assistant at the Institute of Pathology and Anatomy at the University of Heidelberg.

The specimen is then placed in a bath of liquid polymer, such as silicone rubber, polyester or epoxy resin. By creating a vacuum, the acetone is made to boil at a low temperature. As the acetone vaporizes and leaves the cells, it draws the liquid polymer in behind it, leaving a cell filled with liquid plastic. Hardening is the last step in this process and hardening is when the body gets hard.
ReplyDeleteGunther von Hagens was a German scientist that discovered the idea of plastination in 1975. von Hagens thought of the idea of plasination while he was in a butcher shop. Gunther von Hagens was also a teacher and the creator of Body Worlds. In 1974 von Hagens got his medical degree in Pathology and Anatomy. Currently Gunther von Hagens works in a highly concealed lab which creates more displays for Body Worlds.
Plastination is the process of preserving body parts and bodies by replacing fat and moisture with certain plastics, allowing non-decayable bodies and specimens. Silicone, epoxy, and polyester-copolymer are used as curable polymers to preserve the bodies. The polymers replace water and tissue, in order to seal up openings and prevent the bodies from decay. First, the body is preserved using a solution to prevent decomposing. Then, dissections take place, and the specimens taken are put in liquid acetone to draw out water and replace it with acetone. Next, the specimen is put in liquid polymer at a slow boil, causing the acetone to dissolve and forcing the polymer to fill the cells. Then, the specimen is cured with ultraviolet light or gas to harden. Gunther von Hagens' is a German anatomist who completely created the first techniques of plastination, and soon moved onto plastinating the human body. He thought of plastination while watching bodies preserved in an entire block of plastic, and took that idea up a notch. He thought that it would be a better idea to put plastic IN the cells rather than COVERING the cells. He was a research assistant at the University of Heidelberg and he was a lecturer for twenty years.
ReplyDeletePlastination is a process of preserving organic material. Silicon fills up the areas in which water and fat once lived. This process takes approximately one month, depending on the species undergoing the experience. The next step is for the preserved tissue to be dissected and then dehydrated with acetone (an organic solvent) and takes a silicone cleansing under vacuum until the replacement of acetone is completed. This bath culminates nontoxic, odorless, and even enduring tissue. This allows the scientist with easier access without having to worry about extremely fragile material.
ReplyDeleteGunther von Hagens was born in Alt-Skalden/Posen, former Eastern Germany. In 1970-1973, he completed his medical studies at the University of Lübeck, Germany, and later became an anatomist at the Anatomical Institute, University of Heidelberg, Germany. 1977–95 brought about his big break in the scientific field: the discovery of the plastination process. Over the course of 1977-1996, he spoke about his creations, established the Body Donation Programm for Plastination, and founded a plastination center at the State Academy in Bishkek, Kyrgyzstan and at the Dalian Medical University, China; Scientific Director.
Gunther von Hagens was an inspired doctor and anatomist who utilized his knowledge in the expertise field of plastination to create the widely viewed Body Worlds traveling museum exhibit. This display portrays corpses that have undergone the plastination process and is set up for "education and enlightenment". It provides a broad audience with a general, yet hands on experience that helps them understand anatomy, no matter what education background they have had. Von Hagens's "artwork" has been the consequence of a life dedicated to plastination research and two German patents. And like all other renowned artists, his first proposal of the exhibit Body Worlds was rejected. However, one night in 1988, he was working late and found the custodian ogling the plastinated body parts. As of that night, he got a spark of hope, and opened up the exhibit to a selected group, and it was a hit. That was when he realized that he could plastinate an entire body for the world to see.
The fluids and fat are removed and replaced by plastics. There are four main steps in the process of plastination.
ReplyDelete1. fixation
2. dehydration
3. forced impregnation in a vacuum
4. hardening
One of the chemicals that is used is a formaldehyde solution, which will halt the decomposition of the body. If there are any dissections that take place, then the body is put in acetone. In freezing conditions, it will draw out all of the water and replace the insides of cells. In the third step, the body is placed in a "bath" of liquid polymer, like silicone rubber, polyester or epoxy resin. The acetone, that is like a vacuum, will evaporate and leave the cells. "It draws the liquid polymer in behind it, leaving a cell filled with liquid plastic." The plastic must than harden, which gas, heat, or ultraviolet light is needed in order for this to happen properly. Plastination method can be used on anything, from animal organs to humans.
Gunther von Hagens is was founder and creator of the exhibit Body Works. He is also the inventor of the embalming method of plastination. He started his own company, "BIODUR Products, to distribute the special polymers, equipment, and technology used for Plastination to medical institutions around the globe. Currently, more than 400 institutions in 40 countries worldwide use Gunther von Hagens' invention to preserve anatomical specimens for medical instruction. " Before all of this, he was actually in jail because of political reasons. In front of 500 people, he performed the first public autopsy in the UK, in 170 years. He was teacher, and he talked with his donors (including his best friend), who trusted their bodies to him. Gunther would use the bodies for dissection and public display. Because he was a teacher, he wanted to carry the tradition of Renaissance anatomists. He got inspiration from a butcher shop, looking at all of the meat. "A few weeks later, I was to prepare a series of slices of human kidneys for a research project. The usual process of embedding the kidneys in paraffin and then cutting them into thin slices seemed like too much wasted effort to me, as I only needed every fiftieth slice. Then one day, I was in the butcher shop in the university town where I was studying, and as I watched the sales woman slice ham, it dawned on me that I ought to be using a meat slicer for cutting kidneys " "In November 1979, Gunther von Hagens applied for a German patent, proposing the idea of preserving animal and vegetable tissues permanently by synthetic resin impregnation."
Plastination is a technique used in anatomy to preserve bodys. The liquid and fat in the body are replaced with certain plastics so they do not smell or decay. There are 4 steps and the first one is fixation. Fixation is when the body is embalmed in a formaldehyde solution to stop decomposition. Then its time for dehydration, the body is placed in a bath of acetone and under freezing conditions the acetone takes out all the water from the body and replaces it inside the cells. In the third step the body is placed in a liquid polymer bath. By creating a vacuum the acetone is boiling at a low temperature and it starts vaporizing from the cells dragging the liquid polymer behind it leaving a cell filled with liquid plastic. Then the plastic must be cured with heat, gas, or an ultra violet light. Gunther von hagens created plastination.
ReplyDeleteThe word plastination comes from the Greek word plassein, meaning to shape or form. Basically, plastination is a process used to preserve bodies in which water and fat in the body is replaced with a polymer such as silicon, epoxy, polyester, or etc. This process ensures that bacteria will not be able to sustain itself and the body will not decay. There was a small problem, polymer and body fluids are not chemically compatible, so they could not be directly replaced. That is where Gunther von Hagens came in. Gunther von Hagens was born January 10, 1945 in western Poland and grew up in East Germany. He became an anatomist and discovered a solution to the polymer and body fluid problem. The fluids were swapped, the water from the tissues inside the body would be replaced with acetone . Then the polymer replaces the acetone. Von Hagens proposed a different idea, "I was looking at a collection of specimens embedded in plastic. It was the most advanced preservation technique then, where the specimens rested deep inside a transparent plastic block. I wondered why the plastic was poured and then cured around the specimens rather than pushed into the cells, which would stabilize the specimens from within and literally allow you to grasp it." Gunther von Hagens had many previous occupations before he settled as an anatomist. When he was young he had been diagnosed with an uncommon bleeding disorder, and was hospitalized. The environment of the hospital and all the doctors/nurses inspired him to become a doctor himself. He went to medical school in 1965, where he was known for his flamboyant personality. After attempting to cross the border to Austria, he was arrested and went to prison for two years. His relationships with the other prisoners helped him later as a scientist. Later he was freed and finished medical school to take up a hospital as an anesthesiologist. In 1975 he was a lecturer and resident at an Institute of Pathology and Anatomy where he made his plastination discovery.
ReplyDeletePlastination is the process where organic tissues are "plastinated", and no longer decompose. The most popular form of plastination consists of 4 steps:
ReplyDelete1: The tissue is embalmed using formaldehyde so that decomposition no longer will decay the body.
2: The tissue is dehydrated by replacing the water in its cells with acetone.
3: The acetone is then vaporized and is replaced by silicon rubber, epoxy resin, or polyester.
4: The plastic is then hardened by various sources like heat or UV light.
Gunther von Hagens is an anatomist who was the creator of the process of plastination. Gunther first came up with the process of plastination as a process of synthetic resin impregnation for use on animal and vegetable tissues.

Plastination is a method of preserving bodies and other organic tissue.
ReplyDeleteWater and fats are replaced by polymers
Water in tissues are replaced with acetone
Acetone is replaced by polymers
Stimulants polymerize the polymers
Gunther von Hagens created plastination. He though of it when he saw specimens in plastic cubes. He wondered why the specimen conformed to the plastic, and not vice versa.
Plastination is the fixation and dehydration of biological tissue so that way the tissue can be preserved.
ReplyDeleteProcess: The tissue is embalmed in a solution to slow down the process of decomposition. If dissections are needed, they are then performed, and then the tissue is bathed in acetone. In freezing conditions, the acetone draws out the water from the tissue. After this, the specimen is but into liquid polymer to create a vacuum. This sucks the acetone out of the specimen and the polymer then moves into the specimen, filling it was liquid plastic. Finally, the specimen has to be cured with heat or gas to harden it.
Gunther von Hagens is a German scientist how created the process of plastination in 1979. He is the founder of the Body World's exhibit. His past works include being an anatomist and a performer of autopsies.
Plastination is when bodies are preserved using plastic, and the plastic will replace the waters, fats and organic tissues in the body so that it doesn't rot or decay. How does it work?
ReplyDelete1) Cover the body in formaldehyde, this will halt decomposition.
2) The body is then placed in a tub of acetone, which under freezing temperatures, will replace the water and put into the cells.
3) The body is then placed into another tub, except it is filled with liquid polymer. This acts as a vacuum and at a low temperature will boil the acetone in the cells and leave behind a plastic in the cells.
4) The body is then put under an ultraviolet light, gassed, or heated, all to harden the plastic.
Gunther Von Hagens created and patented the idea of plastination. He was an anatomist and worked in a lab until he created the idea of plastination. He wanted to find a way to preserve plant and mammal tissues and created plastination. After his idea was a success he started Body Worlds.
Plastination is a process that is used to preserve the anatomy of any human or animal. In plastination, all the water and fat inside the body is replaced by plastic, which makes the body pretty much incapable of decaying. Plastination is a way to preserve the shape and appearance of the body and all of its organs.
ReplyDeleteThe plastination process is done by this process:
First, the body is embalmed in formaldehyde, then placed in a freezing solution, which replaces the water in the cells.
The body is then placed in a pool of liquid polymer, such as silicon or rubber.
The acetone within the body then starts to boil and evaporate, and is replaced by the plastic solution.
The plastic can then be hardened by UV light or heat, which can harden the body into a certain shape.
Gunther von Hagens is a german anatomist that invented the tissue preservation process known as plastination. He invented this process in 1977, then patented it the next year. He then founded the Institute of Plastination in Heidelberg in 1993.
Plastination is when the water and fat in a body is replaced with certain plastics. This causes the body to have no odor and will not decay. This also allows you to touch it. Plastination is preformed in 4 steps:
ReplyDelete1. Fixation
This is when the body is embalmed using formaldehyde to stop the body from decomposing.
2. Dehydration
The body is dehydrated by replacing water in the body with acetone.
3. Forced impregnation by vacuum
This is when the acetone is vaporized and replaced with plastics. The plastics include silicon rubber, epoxy resin, or polyester.
4. Hardening
The plastic is hardened using heat or UV light.
Gunther von Hagens is the person who created the process of Plastination. This process was invented in 1977 and patented in the year after. The jobs he had in life are an anesthesiologist, and lecturer. Sine 2004 he is a guest professor at New York University College of Dentistry.
Plastination--Waters and fats are removed from the body and replaced with acetone which quickly evaporates. The body is then placed into a vacuum where the pressure is reduced to a point where the solvent boils and the acetone is sucked out the moment it evaporates while the polymere is being absorbed into the cells. This can take a few days if the slice of flesh is thin, or weeks if it is a whole corpse.
ReplyDeleteGunther von Hagens--An anatomy assistant at the University of Heidelberg’s Institute of Anatomy in 1977, Hagens developed and later patented the process of plastination. He had wondered why "the polymer had been poured around the outside of the specimen as having the polymer within the specimen would stabilize it from the inside out." This led him to his first attempt of plastination which resulted in a black, shrunk piece of flesh. The blackening was because of an index refraction of the Plexiglass, and the shrinking was attributed to the solution permeating the flesh too quickly. He remedied this by using rubber silicon and in three, successive baths to keep from curing the tissue too quickly.
what this procedure is, the chemicals involved, and how it is done. Also, who is Gunther von Hagens'? How did he come about with the idea of plastination? What jobs did he have in life
ReplyDeletePlastination is a process used to replace water and fats in a body with plastic so the body will not decay or smell, but the body will retain its original properties.
Chemicals used include "curable polymers" such as silicone, epoxy, and polyester copolymer. These replace water and lipids. Also, specimens are placed in formaldehyde and acetone solutions, and eventually in liquid polymers, such as silicone rubber, polyester, and epoxy resin.
Gunther von Hagens was an anatomist from Germany who patented the idea for preserving biological tissues using plastination. He got his idea when he was looking at organs that had been preserved by surrounding them in plastic, and he said, "I wondered why the plastic was poured and then cured around the specimens rather than pushed into the cells, which would stabilize the specimens from within and literally allow you to grasp it." -http://www.bodyworlds.com/en/gunther_von_hagens/life_in_science.html
He worked at the Institutes of Anatomy and Pathology as a lecturer for 22 years after he had received a medical doctorate. He founded the Institute of Plastination, which focuses on creating the specimens.
Plastination is a process used to preserve organic material. Plastination usually takes about one month. In the first step, the tissue is embalmed i a formaldehyde solution to halt decomposition. Tissue is dissected and then dehydrated using acetone. It is then placed in a silicone bath under vacuum until the acetone is completely replaced. After plastination, the toxic fixatives are eliminated and the tissue is safe to handle.
ReplyDeleteGunther von Hagens was a German anatomist who invented the method for plastination. The idea came about after Hagens thought there was a better way to preserve specimens than encasing them in a polymer block. He announced in January 2011 that he was dying of Parkinson's Disease and planned to contribute his body to the Body Worlds exhibit when he dies.
Plastination is a process used to preserve human bodies. In this method, water and fat in the body are replaced by plastics, preventing the body from decay, stench, and other natural process. In plastination the body goes through four steps of preservation: fixation, dehydration, forced impregnation in a vacuum, and finally hardening.
ReplyDeleteGuther von Hagens is an anatomist whom was born in Skalmierzyce, Poland. He is well know for his invention of the technique of plastination, which he created to preserve animal and vegetable tissue.
Plastination is a technique used in anatomy to perserve several bodies or body parts for a purlonged period of time. Water and fat are replaced with plastic, and do not smell of decay. There are four main steps to this:
ReplyDelete1. Fixation
2. Dehydration
3. Forced impregnation in a vacuum
4. Hardening/ Positioning
Fixation is started when a body is inserted with embalming fluid (Formaldehyde typically), which is also a technique to perserve skin tone for funerals. This will halt the skin tone decompisition. Dehydration is exactly what the word means, draining the water from the body. The specimen is dipped and placed in an acetone bath. The acetone is then freezed with the body in it. The frozen liquid then takes in all water or liquid inside the specimen. Forced impregination makes the specimen be placed inside a bath of liquid polymer. The polymer usually contains the chemicals Silicon Rubber, Polyester, or Epoxy Resin. This creates a vacuum, which makes the liquid acetone to boil and evaporate, drawing the polymer behind it. It leaves the cell with plastic. The plastic is then heated up in order to maake it harden.
Gunther Van Hagens is the creator of plastination. He had the idea of perserving vegetable and animal tissues permenantly with poly-resin impregnation. He tried the process that we now call plastination. He was successful. Earlier in his life, he studied medicine for five years. He was an anatomist, but then came upon the idea of using resin to perserve tissues.
Plastination is the procedure to preserve bodies or various body parts. What happens it that the body liquid and fat is replaced with certain plastics. This technique was first introduced by Gunther Von Hagens, an anatomist who started his work by trying to find a way to preserve animal and vegetable tissues. When he eventually invented and patented the idea of plastination and created Body Worlds.
ReplyDeleteThe steps of Plastination:
1. The specimen is covered in formaldehyde to halt decomposition.
2. All of the liquid in the body is taken out and replaced by acetone
3. Then the body/body part is placed in a vaccum like container and when the acetone is sucked out it is replaced by either silicon rubber, polyester, or epoxy resin.
4. The plastic then needs to harden, resulting in a plastinated body.
Tomorrow we will be viewing bodies that have undergone a procedure known as Plastination. I would like to research what this procedure is, the chemicals involved, and how it is done.
ReplyDeleteWhat is the point of plastination?
Plastination is an anatomical method to preserve human bodies. It withholds any odor and rotting, can be touched, and keeps the old shape of the body.
What are the chemicals involved in plastination? How is plastination done?
Plastination involves formaldehyde to embalm it to stop it from rotting. Then, the body is soaked in acetone, which replaces all the cells with water. A liquid polymer bathes the body, and then the scientists create a vacuum, boiling the acetone and leaving the polymer. It is then hardened with a heat or UV rays.
Also, who is Gunther von Hagens'? How did he come about with the idea of plastination? What jobs has he had?
A West German, he is an influential anatomist who has had an interesting path through life. As a hemophiliac, he was hospitalized at a young age due to his condition. In his adulthood, he sneaked into the then-Communist Bulgaria and Hungary as a vacationing student. He was caught when trying to get into Czechoslovakia, and was promptly jailed for two year. West Germany bought him out, and he was soon an anatomy assistant. He wondered why scientists didn't preserve bodies from the inside out. A few weeks later after thinking about this idea, he experimented with a kidney. The preservation worked, but the kidney blackened. After experimenting, he finally figured out how to preserve it without loss of color. This process is now called plastination. He then created the Institutes of Plastination in Germany, Kyrgyzstan and China. He spearheaded the BodyWorlds concept, and has also been a speaker at many colleges since.
Plastination is the process of hardening a dead specimen's organ through dehydration. Waters and fats are replaced by plastics, and the body no longer decays nor becomes malodorous; it is also touchable.
ReplyDeleteThere are four basic steps in plastination.
First, any water and fats in the body are replaced by polymers.
Second, the water in the body's tissue is replaced with acetone.
Then the acetone is substituted for polymers.
Finally, the polymers are polymerized by stimulants.
Gunther von Hagens was the man who came up with the process of plastination. He came up with it when studying some specimens preserved in blocks of plastic, which was the most advanced technique for body preservation at the time. He began to wonder why the plastic was poured AROUND the specimen, rather than directly INTO it. That way, he reasoned, one could actually touch and feel the specimen. von Hagens had developed an interest in medicine/medical science after he was hospitalized for six months as a child. He grew up to go to medical school, and there became involved in politics. He spent two years in jail after attempting to cross the Austria-Czecoslavakia border, and returned to West Germany to finish medical school upon his release. He became an anatomist, and then went on to develop plastination.
4 steps in plastination:
ReplyDeleteFixation- a formaldehyde solution is used, this stops the decomposition of the body
Dehydration- the body is placed into acetone, this is calle Freeze substitution, during this process tissue water is replaced by the acetone over a span of about a month
Forced impregnation- the body is placed in liquid polymer then placed under a vacuum that removes the acetone and lets the polymer set into place
Gas Cure/Hardening- the body comes into contact with curing gas, after 48 hours it is dry to touch. After a few months and the curing is complete the body can then be stored at room temperature.
Von Hagens lived in Germany and developed plastination in 1977, it was patented a year later. He received a doctorate from the University of Heidelberg in 1975.
Plastination is the procedure done to a corpse that prevents it from decaying naturally and allows it to be posed and manipulated. This is achieved by replacing the body's water and fat by special plastics such as silicone, epoxy, polyester-copolymer. First the body is mummified in formaldehyde so it won't decay. After the body is dissected, it is soaked in freezing acetone, which robs the corpse of its water. The body is then bathed in liquid plastic, and the acetone is boil into vapor. The plastics then flow in and replace the acetone. Once the body is hardened from exposure to gas, heat, or ultraviolet light, it has been plasticized.
ReplyDeleteGunther Von Hagens is the German anatomist who discovered plastination. He was a lecturer at the University of Heidelberg for 20 years.
plastination is the act of replacing the fluid in ones body with silicone rubber, and preserving it.The plastination process consists of pumping formalin into the body to halt decay, and to sanitize it, and then removing the skin, and fatty tissue.
ReplyDeletenext come the removal of body water and dissolvable fats, by placing the body in an Acetone Bath, after this the body is placed in a vacuum sealed bath, this time full of liquid polymer like silicone, and then the acetone is removed using the vacuum, the silicone replacing it. finally, the body is put into position by using hooks, wires, and foam blocks, then hardened, depending on what kind of polymer used, gas, heat, or light can be used.
Guther Von Hagens is the inventor of the process of plastination, he came up with the idea after seeing his first specimen inside of a polymer block, and wondered why they didn't just place the polymer inside, since it would preserve it from the inside out that way. When Guther tried his first experiment, he just soaked a slice of kidney in an acetone curing agent, then sucking it out with a vacuum. His first experiment turned pitch black and shrunk, he tried the same experiment later, but using silicone instead.
Plastination is a method of preserving a body by turning body waters and fat to different types of plastic and therefore making it so the body does not decay, breakdown, or smell. The four steps in plastination are fixation, dehydration, forced impregnation in a vacuum, and hardening. first, the process of decay is stopped by embalming, usually with a formaldehyde solution. The specimen is then submerged in acetone, which removes all of the water from the body. Then, the body is placed in a bath of liquid polymer and is vacuum sealed and brought to a low boil. This leaves the cells filled with various types of plastic. Lastly the body is cured by gas, heat, or ultraviolet light to harden.
ReplyDeleteGunther von Hagens is an anatomist who invented the method of preserving specimens with plastination. Hagens was inspired to join the medical field after being hospitalized for six months as a child for an uncommon bleeding disorder, Haemophilia, and looking up to the doctors and nurses at the hospital. Through his discoveries, he created the Body Worlds exhibit, a traveling museum that displays examples of plastination.
