Bel-Art Tabletop Büchner Funnel 18 Inch

The Bel-Art Table Top Büchner Funnel 18 Inch is a large-format polyethylene filtration funnel designed for compatible laboratory and industrial filtration setups. Published product information describes compatibility with Fritware porous filter plates or perforated filter plates, allowing the filtration surface to be configured for different procedures and filter media.

The Bel-Art Table Top Büchner Funnel 18 Inch uses a removable hose-barbed connector intended for 12.7 mm (1/2 inch) inside-diameter tubing and threaded into a 3/4-inch NPT bung. Fritware porous plates are supported by a multiple-ring grid and are listed in medium 45–90 micron and coarse 90–130 micron porosities. Perforated HDPE plates provide an alternative surface for compatible filter cloth or paper.

Material and temperature limitations should be considered before using the Bel-Art Table Top Büchner Funnel 18 Inch. Existing specifications identify polyethylene/HDPE construction and a published operating range for the Fritware plates of approximately -80°C to 52°C (-112°F to 125°F). Confirm chemical compatibility for the specific liquid, solvent, cleaning agent, and process conditions.

Inspect the funnel body, plate, hose connection, sealing surfaces, and tubing before operation. Use appropriate receiving equipment and ensure that any vacuum components are rated for reduced-pressure service. Large filtration assemblies should be positioned securely to prevent tipping, hose strain, or accidental movement during use.
