Corning – Pyrex – Desiccators
Desiccators have a rugged 24/29 standard taper stopcock with a tooled hose connection that serves as the vacuum inlet. It is designed so that its manipulation is not affected by the vacuum.
Component Materials
Type I Class A – Low-Expansion Borosilicate Glass, per ASTM E438 (Standard Specification for Glasses in Laboratory Apparatus)
Attributes
Product Dimensions – 270 mm Flange OD x 107 mm High
Autoclaving
This product will withstand repeated standard autoclave cycles of 121°C at 15 psi for 15 minutes. Due to the thick
walls on this product, it is CRITICAL that the heating and cooling cycles bel slow and even.
Heating/Cooling
This product should NOT be heated while being used in a vacuum or pressure application as the combination of
thermal and mechanical stresses could cause a failure.
Vacuum/Pressure
This product is designed for full vacuum of 760 mm Mercury (15 psi negative pressure).
This product is not designed for and is not rated for pressure applications.
