Drierite desiccants are made from the naturally occurring mineral, gypsum (calcium sulfate), and are available in several varieties designed to solve all types of drying problems.

Dry-Seal safety desiccators are fitted with a simple, efficient and unbreakable valve of PTFE, eliminating the need for a glass stopcock with its ground joint entry.

Nalgene desiccator has a transparent polycarbonate cover and polypropylene base that will not shatter or implode at full vacuum and Teflon® stopcock.
