Paraffin wax reagent Surgipath Paraplast

for histology

Paraplast
Paraplast is recommended for general tissue embedding. It is a refined blend of highly purified paraffins and plastic polymers of controlled molecular weight to improve tissue infiltration and deliver high-quality sections with minimal compression. Paraplast increases elasticity of brittle, difficult-to-section tissue, promoting wrinkle-free sections.

Paraplast Plus
Paraplast Plus is recommended for large specimens or tissues that commonly present infiltration challenges. It contains a small percentage of dimethyl sulfoxide (DMSO) to accelerate tissue penetration.

Paraplast Xtra
Paraplast Xtra is formulated for lower-temperature infiltration to help prevent tissue distortion. It combines low molecular weight polymers and highly purified paraffins to resist compression and improve ribbon continuity; its low viscosity enables complete infiltration of dense tissue.
