Forma-Scent® Fixative

This Forma-Scent® fixative is for use in histological applications of fixation and storage of tissue specimens. Although the Forma-Scent® fixative masks formalin odor, fumes are still dangerous and should be avoided.

Prefilled Formalin Containers

These clarified, polypropylene wide-mouth containers are flexible, crack-resistant and autoclavable and allow visualization of specimens. Select sizes are available with a pressure-sensitive inner seal that protects against leakage and reduces exposure to formalin vapors.
