Rubber Conical Gasket Guko, made from EPDM, for filtering flasks, Ø 61 mm

One of the most important separation methods in the laboratory environment is filtration, which is used to separate or clean different media. For this working method, filters are required which are selected according to the application with regard to size and porosity. These EPDM conical gaskets are used to mount a Gooch crucible into a crucible funnel adapter or a Büchner filter funnel onto a filter flask to create a gas tight seal that allows vacuum filtration.
