msdsPolyform-F Free-Flowing Granules arrow12Polyform-F™ Free-Flowing Granules

For Accidental Spills of Formaldehyde, Glutaraldehyde & other aldehyde solutions

Protection against formaldehyde and glutaraldehyde vapor has never been easier!

Polyform-F is the spill control product of choice for the safe and rapid control of harmful vapors from Formaldehyde, Glutaraldehyde, 10% Neutral Buffered Formalin, and other aldehydes, including Cidex-OPA and Formaldehyde based embalming solutions. Once Polyform-F free flowing granules are applied, the harmful vapors are eliminated in 2 to 3 minutes. Formaldehyde and other aldehyde solution are neutralized and polymerized. This safe reaction leaves a non-hazardous biodegradable polymer, safe and simple for personnel to clean up and dispose of.

Polyform-F may be used in conjunction with Formalex liquid control agent in a spray bottle, for very small spills, vapor control for trash cans, and for hard to reach areas affected by the spill, such as cabinet faces and drawers.

FAN Pad-GLarrow12FAN Pad-GL™ Formaldehyde Absorbent Neutralizer Pads

Absorbs & Neutralizes Formaldehyde & Glutaraldehyde, destroying their hazardous vapors

These super absorbent pads are specially treated with Formalex and designed for the ultimate destruction of formaldehyde, 10% NBF formalin, and glutaraldehyde solutions. They were designed to facilitate the reduction of formaldehyde vapors by absorbing and neutralizing formaldehyde, glutaraldehyde and other aldehydes. They provide excellent vapor control during gross examination, dissecting, transporting, or transferring formalin fixed tissue. They are also used for vapor control in storage of formalin, formalin fixed tissue containers and for small formalin spills. Once the formalin solution is absorbed, the FAN Pad GL will convert formaldehyde and other aldehydes to a non-hazardous polymer, eliminating the source of harmful vapors making the work area a lot safer. Effective moist or dry, they are the safest and most effective method of controlling air quality in
