VWR Vacuum desiccator, Borosilicate 3.3 glass, With stopcock, 300 DN, 380×435 mm

DIN 12491 Certified High-Strength Desiccators for Vacuum Drying and Storage

VWR® Vacuum Desiccators are made from borosilicate 3.3 glass and designed for maximum vacuum retention, mechanical strength, and chemical durability. They feature precision-ground flanges and interchangeable tubulated lids with NS 24/29 standard ground joints and PTFE stopcocks, enabling safe, airtight vacuum operation in demanding laboratory environments.

These desiccators are ideal for use in moisture-sensitive sample storage, drying under reduced pressure, and vacuum filtration setups. Their robust wall thickness supports maximum technically feasible vacuum levels, and the flat flange design ensures tight sealing between the base and lid.
