Buchner Funnel 914mm Replacement Coarse Plate
Porous filter plate Buchner funnels available with medium porosity (45-90 microns) or coarse porosity (90-130 microns). Fixed and removable filter plates are 6.4mm (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 or removable punctured filter 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. A removable filter plate allows easier cleaning and precious metals recovery. 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 52°C (125°F). 24" and 36" sizes come crated. Custom sizes, shapes, features and accessories including lids and filter paper hold down rings can be made to order.
