Desicator Vacuum 24cm, borosilicate glass with porcelain plate-EIS-CH0363C

• Made from heavy-duty borosilicate 3.3 glass.
• Clear top with large space to maximize interior clearances.
• Holds a full vacuum (740mm Hg 20cm) at room temperature for 24 hours.
• Includes 214mm (8.4") porcelain sieve plate that rests on the 240mm (9.4") I.D. chamber bottom, and removable glass stopcock with side arm allowing a controlled entrance of air while preventing unnecessary turbulence.
• Superior chemical durability and heat tolerance. Designed for use in professional laboratories, but is an ideal choice for science classrooms and household use.

Large Vacuum Desiccator holds a full vacuum (740mm Hg 20cm) at room temperature for 24 hours - will remain airtight even if not under vacuum. Top, bottom, and stopcock are made of high quality semi-frosted borosilicate 3.3 glass. Includes 214mm (8.4") diameter porcelain sieve plate which sits at the bottom of the chamber, whose effective inner diameter measures 240mm (9.4"). 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: 302mm (11.9") O.D. x 310mm (12.2)"H.

Autoclavable, with superior chemical durability. Low temperature gradient - can withstand high temperatures & thermal shocks. Eisco Labs Borosilicate glass has the following heat tolerances: Strain Point 515°C | Annealing Point 565°C | Softening Point 820°C
