Buchner Funnels

A Buchner funnel is a piece of laboratory equipment used in suction filtration. Our Buchner funnels come in three main varieties: standard (with fixed or removable plates), single piece, and two piece (easy to clean). Buchner funnels are all intended for use below 52° C (125° F) and are suitable for a variety of lab procedures.

  • Standard porous filter plate Buchner funnels are available with medium porosity (45-90 microns) or coarse porosity (90-130 microns). The fixed or removable filter plates are 6.4mm (1/4") thick HDPE with a non-porous circumference to help fasten filter paper to the plate. These Buchner funnels are also available with a punctured filter plate, also HDPE, which 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.
  • Single Piece Filtering funnels have a welded-in, Fritware® porous polyethylene filter plate (fine, medium or coarse) but can also be used with a filter paper.
  • Two piece Buchner funnels are autoclavable, economical and lightweight. They can be separated for effortless washing.
