Product Description
Holding a deep vacuum on a storage vessel for days requires a valve that does not leak or contaminate the contents. This AIRLESS-WARE adapter fits a PTFE vacuum valve directly into a flask joint, keeping evacuated or inert-filled vessels sealed until you need them.
This listing is for Kimble catalog number 211450-2440: AIRLESS-WARE Vacuum Valve Adapter, 24/40. The adapter is made from low-extractable, 33 expansion borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. Its KONTES PTFE vacuum valve minimizes contamination and maintains vacuum in the micron range, with the valve tip seal directed toward the storage vessel. This model has a 24/40 standard taper joint. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
