Filtering Funnels

For positive pressure filtration of materials up to 15 psi. Connection between the funnel and adapter is made by an o-ring joint which permits a larger, grease free opening for sample retrieval.

Specifically designed for use with 18, 24 and 36 Buchner Funnels, apply slight downward pressure and ‘sweep’ the trowel along the surface of the precipitate to quickly and efficiently smooth fissures appearing during the filtration process. Large"

Unsurpassed for non-vacuum, high-speed filtration, these clear funnels have internal helicoid ribs to increase the filtration speed. Vertical outer ribs prevent airlock Autoclavable polymethylpentene plastic unaffected by corrosive liquids Heat
