Technovit® H7100 GMA EMBEDDING KIT Technovit® Glycol Methacrylate embedding kits developed by Kulzer in Germany are the most convenient to use, and offer the best embedding results. Features Technovit® GMA kits give better results offering improved morphology, and allow for 1 micron serial sectioning. Technovit® 7100 GMA is less sensitive to O2 during polymerisation so sealing of the moulds is not necessary. The polymerisation temperature never exceeds 40°C, making Technovit® a potential choice for enzyme histochemistry. The consistent high quality of raw materials used to make the resin allows for a permanent clear colourless block and reproducible results.
