Paramat paraffin wax

Paramat is the original British combination of paraffin wax and plastic polymers, which has been used in histology labs around the world for over 20 years. It has been discovered that when plastic polymers are added to paraffin, the elasticity of the final block is increased when compared to paraffin alone. In addition, the mixture improves tissue penetration, makes section ribboning easier, has a lower tendency to crumble, and produces better overall outcomes with fibrous tissue.

The addition of a small quantity of dimethyl sulphoxide (DMSO) to Paramat has resulted in PARAMAT EXTRA. This formulation has additional advantages, such as faster tissue penetration and a more homogenous matrix to support the specimen.
