Paraplast is recommended for general tissue embedding. It is composed of a refined mixture of highly purified paraffin-containing plastic polymers of regulated molecular weights. This supports improved tissue infiltration and quality sections with minimal compression. Paraplast gives brittle, difficult-to-section tissue an innate elasticity, promoting wrinkle-free sections.
Paraplast Plus is suggested for large tissue or tissue that may normally present infiltration issues. Paraplast Plus contains a small percentage of dimethyl sulfoxide (DMSO), allowing accelerated tissue penetration.
Paraplast Xtra is recommended for lower temperature infiltration which aids in the prevention of tissue distortion. It is composed of a unique blend of low molecular weight polymers and highly purified paraffins for compression resistance and ribbon continuity. Low viscosity permits complete infiltration of dense tissue.
