• Made from heavy-duty borosilicate 3.3 glass.
• Inner diameter of the chamber measures 15cm (5.9")
• Holds a full vacuum (740mm Hg 20cm) at room temperature for 24 hours.
• Includes 132mm (5.2") porcelain sieve plate that rests on the 155mm (6.1") I.D. chamber bottom, and removable glass stopcock with side arm allowing a controlled entrance of air while preventing unnecessary turbulence.

Vacuum Desiccator holds a full vacuum (740mm Hg 20cm) at room temperature for 24 hours - will remain airtight even if not under vacuum. Chamber, lid, and stopcock are made of high quality semi-frosted borosilicate 3.3 glass. Includes 132mm (5.2") diameter porcelain sieve plate which sits at the bottom of the chamber, whose effective inner diameter measures 15cm (5.9"). The removable glass stopcock with side arm measures 105mm H x 56mm W and allows a controlled entrance of air preventing unnecessary turbulence. Overall desiccator size without stopcock: 210mm (8.25") O.D. x 218mm (8.6)"H.
