PYREX® Vacuum Desiccators
PYREX® vacuum desiccators have a rugged standard taper external sleeve with a tooled hose connection that serves as the stopcock. Ideal for routine laboratory sample drying. It is designed so that its manipulation is not affected by the vacuum. The open position is indicated by the molded arrow on the cap. A quarter turn from this position closes the desiccator. For ease in use and improved performance, it is recommended that the standard taper sleeve be lubricated with a silicone-based vacuum grease. Warning: Do not heat or subject to pressure. Rated 1-atmosphere vacuum.
