These replacement discs are made for use with our Polypropylene Buchner Funnels. Made from high density polyethylene (HDPE) plastic, these discs have excellent chemical resistance and are useful for holding up filter paper. In this way the blocking of the holes is avoided and the filtering surface of the funnel is free. Will withstand temperatures up to 110°C. Mesh size 950 x 700 microns.
* Plastic Buchner Funnels and Buchner Funnel Adapters are also available, sold separately
