Epoxys

This mixture is less viscous than the final embedding mixture of EMbed-812.

Electron Microscopy Sciences' replacement for the discontinued Epon-812. Produces the same results in terms of preservation, handling, sectioning, and staining as the old Epon-812.

Provides excellent penetration for embedding biological tissues and rapid infiltration.

A water miscible epoxy resin used for both light and electron microscopy. Its low viscosity permits easy infiltration and embedding, and yields light-colored blocks.

An aromatic polyepoxide, a colorless resin of relatively low viscosity, with virtually no shrinkage.

Luft's Formula. Polymerization takes place overnight so blocks can be sectioned the next day. J. Biochem. Biophy. Cytol. 9, 409 (1961).

Also known as American Araldite. The blocks are slightly harder than those produced by Araldite 502.

Mollenhauer Epon-Araldite Formula. For hard blocks and high image contrast. Blocks are easily sectioned. Stain Tech., 39,11 (1964)

Three different mixtures: one for relatively soft blocks, another for harder blocks for collagenous tissue, and a tougher one if required.
