Büchner funnel with porous filter plate
Large volume, one piece design
Rugged and rigid polyethylene construction, ideal for heavy use
The filter plates made of HDPE (high density polyethylene) have a porosity of 45-90 µm and a thickness of 6.4 mm (1/4"). They are removable and allow an easy cleaning. All plates are supported by a multiple ring grid to prevent displacement under vacuum.
Vacuum connector fitting accepts 12.7 mm (1/2") I.D. tubing. The tube fitting is fixed on the 260 mm funnel and threads into 3/4" diameter NPT bung on all other models.
All Büchner funnels are rated for use below +50 °C.
