Drierite

Drierite is a type of desiccant — a material used to remove moisture from gases or liquids. It is typically composed of calcium sulfate, often coated with cobalt chloride, which changes color when it absorbs moisture, providing a visual indicator of dryness. Used in laboratories and industrial processes, Drierite helps maintain dry conditions, preventing equipment corrosion or chemical reactions that require low humidity. It is stable, reusable after drying, and effective at absorbing water, making it a reliable choice for moisture control in various scientific and technical applications.
