Desiccators lab

Desiccators lab

Desiccators are specialized laboratory glassware designed to store moisture-sensitive materials and perform controlled drying under ambient or vacuum conditions. Constructed from borosilicate glass 3.3, these desiccators provide excellent chemical resistance, thermal stability, and transparency for easy observation.

Available in standard and vacuum-capable models, they feature precision-ground flanges, PTFE spindles or stopcocks (for vacuum models), and knob tops (for standard models), ensuring airtight sealing and reliable operation. Ideal for chemical, pharmaceutical, biological, and analytical laboratories, desiccators protect samples from ambient humidity, moisture ingress, and contamination.
