Table-top Buchner funnels with medium porosity (45-90 microns) fixed filter plates are 6.4mm (1/4") thick high density polyethylene with a non-porous circumference to better fasten filter paper to the plate. The high density polyethylene rigid plate is 4.8mm (3/16") thick. Holes are 4.8mm (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. Vacuum connector fitting accepts 12.7mm (1/2") I.D. tubing. The tube fitting is fixed on the 260mm (10.25") funnel and threads into 3/4" diameter NPT bung on all other models. All Buchner funnels are rated for use below 52ºC (125ºF). 24" and 36" sizes come crated. Large volume, one piece design. Rugged and rigid polyethylene construction, ideal for heavy use.
