Use of physical and chemical factors in the development of plastination anatomical preparations

The fundamental invention of von Hagens, known as plastination, allows the creation of safe for human health anatomical preparations. In biological material preparation are used chemical or physical factors to replace tissue fluid by silicone derivatives or polyester. They stop the destruction of tissues, which began after the death causative by microorganisms from the external or internal environment, and their uncontrolled enzymes too. Tissue fluid from the biological material is extracted by chemical dehydrators, silicones impregnate tissue forcefully in conditions of low temperature and low pressure. Drying in plastination S10 technique is carried out with the fumes of chemical compounds. For hardening in P40 technology for preparation of brain plates UV-rays are used.
