These PYREX® desiccators have a rugged 24/29 standard tapered stopcock with a tooled hose connection that serves as the vacuum inlet.

• The tubulation Ext.Ø is approximately 10 mm
• Material is Borosilicate Glass Code 7740
• This design eliminates the need for grease

It is designed so that its manipulation is not affected by the vacuum. To introduce vacuum into the desiccator, loosen the stopcock to disengage the PTFE plug from contact with the glass. A half turn from this position closes the desiccator.
