General description

Paraplast® is a paraffin–polyisobutylene mixture for tissue embedding and infiltration. It is a refined combination of highly purified paraffin with plastic polymers. It produces minimal tissue compression and wrinkle-free sections and cuts to 4 μm thickness with excellent ribbon continuity.

Application

Paraplast® has been used for tissue embedding and in the following applications:
  • to screen major groups of vertebrates for the presence of cardiac smooth muscle and its phylogenetic distribution in terrestrial and aquatic turtles
  • to study the relationship between membrane impedance and dendrite length of hippocampal neurons
  • to compare the regenerative properties of human stem cells of the apical papilla as an alternative to other dental stem cells

Features and Benefits

  • Minimal tissue compression.
  • Produces wrinkle-free sections.
  • Excellent ribbon continuity.

Other Notes

Double filtered paraffin wax in pellet form.
