Application

Epoxy Embedding Medium (Epon_812 substitute) is a very widely used embedding resin for electron microscopy, as it penetrates into the tissue specimen faster than Araldite and other polymers due to its low viscosity. Epoxy can be hardened easely and uniformly at low temperatures by the addition of DDSA, NMA and the accelerator DPM-30. Slight shrinkage does occur during curing. Epoxy embedding medium is useful for embedding a variety of tissues as a wide hardness can be obtained with this resin to suit a specific tissue type by using two different anhydride curing agents (DDSA and NMA). Universal embedding medium for semi- and ultrathin sections.
