General description

Ascarite® is sodium hydroxide coated silica mainly used as carbon dioxide adsorbents. It is the second generation of the original Ascarite, which was derived from granular asbestos. Ascarite rapidly and quantitatively adsorbs carbon dioxide, (and acid gases), and is useful in a number of analytical and microanalytical procedures, physiological studies, etc.

Application

Ascarite® can be used as a carbon dioxide (CO2) trap.

Features and Benefits

The material is self-indicating, gradually changing color (to white) within a narrow zone due to the formation of sodium carbonate.
