产品介绍

环氧树脂Epon-812，曾经是电镜科学领域应用最为广泛的包埋树脂，Shell Chemical公司曾经生产。现在该公司已经不再生产Epon-812了，许多与Epon-812具有近似特性的替代品相继问世。经研究发现下述文章中所进行的实验得到大家高度一致的评价：

EMS公司特别推荐和生产了EMbed 812包埋剂，利用它可以得到同样高质量的切片。EMbed 812包埋剂的Specific Gravity:为1.08-1.10。

使用时注意，EMbed 812 可能会腐蚀所接触到的塑料。应用Epon-812树脂的所有配方均适用于Embed 812，例如Luft's 配方， Mollenhauer's and EPON-ARALDITE 混合物配方。 

EMbed 812包埋试剂盒，试剂盒内含物：

450ml EMbed-812
450ml DDSA; Specially Distilled
450ml NMA

*50ml DMP-30
