Polysciences has been the leader in supplying epoxy embedding material to microscopists for many years. Our Poly/Bed® line of products are the reliable, long-established means by which you can be assured of secure specimen embedment. Use Poly/Bed® for your scientific studies requiring beam stability, low shrinkage, and good contrast. Poly/Bed® Epoxy formulations are of lower viscosity then Araldite formulations, and hence provide better penetration into tissue samples.This kit configuration provides even lower viscosity, and faster diffusion and penetration, than the standard Luft formulation.Kit Contains: 1x200ml Poly/Bed 812, 1x160ml Dodecenyl Succinic Anhydride (DDSA), 1x100ml Nadic Methyl Andydride (NMA), 1x20ml BDMA (Benzyl dimethyl amine)
