Technovit 7100: Easy to use. Reproducibility and reliability in embedding. A resin embedding system based on HEMA* (2-hydroxyethyl methacrylate). The hydrophillic resin is used for example in botany, zoology and in the industry for embedding tissues for light microscope studies. The sections can be used for histological staining and enzyme detection. Technovit® 7100 transparently polymerises. Uniform thin sections can be made out of the blocks with the rotation microtome. It is not necessary and also not possible to elute the plastic out of the block and the section. The chemical polymerisation of Technovit® 7100 is initiated using a barbituric acid derivative in combination with chloride ions and benzoyl peroxide. The catalyst system does not have any aromatic amines compared to traditional systems.
