Product Description
Leaks around a support screen let unfiltered liquid bypass the membrane and compromise results. These PTFE gaskets seal the stainless steel screen into a 47 mm support base, so every drop is drawn through the filter during vacuum filtration of aqueous or solvent-based samples.
This listing is for Wheaton catalog number 419366: PTFE Support Screen Gasket for 47 mm Assembly, Case of 6. Made from PTFE, the gaskets resist virtually all common lab chemicals and solvents and do not add contaminants to the filtrate. They fit 47 mm stainless-support filter bases and screens and are packed six per case, giving spares for routine replacement when gaskets become deformed or worn. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
