Description: Funnel with Medium Porosity Fixed Plate. Porous filter plate Buchner funnels available with medium porosity (45-90 microns) or coarse porosity (90-130 microns). Fixed filter plates are (1/4) thick high density polyethylene with a non-porous circumference to better fasten filter paper to the plate. Inquire about other porosities. Buchner funnels are also available with a fixed punctured filter plate. The high density polyethylene rigid plate is (3/16) thick. Holes are (3/16) diameter on 11mm (7/16) centers. The fixed plate models can be used for coarse filtration or with a cloth or paper filter. All plates are supported by a multiple ring grid to prevent displacement under vacuum.
