Applications
Used as a replacement lid for smaller desiccators (Ø 150 mm) that require stopcock connection for vacuum drying or inert atmosphere storage.
Ideal in laboratories where precise moisture control is needed for hygroscopic materials, sensitive reagents, or post-heating sample cool-down.
Suitable for educational, research, pharmaceutical, or industrial labs requiring desiccation under controlled pressure or atmosphere.
Maintenance & Handling Tips
Before use, apply a thin layer of vacuum-grade grease to the ground-glass flange to ensure an airtight seal.
Regularly inspect and clean the stopcock valve to ensure proper operation and prevent leaks.
Avoid sudden temperature changes (thermal shock) to prevent cracking of the glass.
Clean with mild detergent, rinse thoroughly, and allow to dry completely before re-assembly.
Store the lid separately or on a stable surface to prevent chipping of the ground edge.
