Drierite Desiccants

Indicating DRIERITE in this plastic unit dries air and gases for small scale laboratory applications. A rubber hose connection provides an immediate flow of dry gas. Note: Do not use this plastic unit in the presence of vapors or liquids containing phosphate esters, synthetic lubricants, hydrocarbon solvents, methanol, acetone, lacquer solvents, or other organics.

Color Change
Indicating DRIERITE is a distinct blue color. When its drying capacity is exhausted, it turns to pink. Indicating DRIERITE gives constant visual assurance of active desiccant.
