Paraformaldehyde is the condensation product of methylene glycol, a substance not so far isolated in its pure form; it is a white solid with a formaldehyde content between 78 and 98% and is supplied either as a Prill or Granular.
All forms contain more than 95.5% paraformaldehyde content. The Prill and Granular forms are small, free-flowing, dust-free beads, the most desired by EM users.
A fast-penetrating EM fixative used in combination with Glutaraldehyde, Acrolein, and Osmium Tetroxide.
