Pyrex® Desiccators with ST 24/29 Stopcock
By CorningThese Pyrex® desiccators have a rugged 24/29 ST stopcock with tooled hose connections that serves as the vacuum inlet. 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. Desiccators are designed to eliminate the need for grease. The tubulation O.D. is approximately 10mm. Complete units are available for purchase, as well as replacement covers and stopcocks.
Do not heat or subject to pressure. Rated 1- atmosphere vacuum.
