THE FEATURES AND BENEFITS OF OUR FILTER FLASKS

Manufactured with heavy walls to provide increased mechanical strength to withstand differential pressures when used under vacuum, the Pyrex® Büchner filter flasks are available with either an integral glass side-arm or a PTFE screwthread tubing connector. Complying with the requirements of ISO 6556, these flasks are designed to be used in conjunction with a Büchner funnel (these are available in our Pyrex® and Quickfit® ranges). The Quickfit® Büchner filter flasks feature a conical ground glass neck joint that is fully interchangeable with other products in the Quickfit® range and, like the Pyrex® filter flasks, are available with either an integral glass side-arm or a PTFE screwthread tubing connector.
