Description
Büchner funnel Ø 240 mm is a glazed porcelain laboratory funnel intended for vacuum filtration with filter paper of 240 mm diameter. Built to DIN 12905, the classic Büchner design features a perforated plate that supports the filter medium during suction filtration of precipitates, crystals and suspensions. The fully glazed porcelain body combines chemical resistance with mechanical robustness for everyday wet-chemistry work in analytical and preparative laboratories. At 240 mm diameter the funnel handles larger batch volumes and supports efficient solid–liquid separation after precipitation or crystallisation. Supplied as one piece with a net weight of 4,51 kg, this funnel from manufacturer Witeg fits standard filtration assemblies using rubber cones or adapters on filter flasks. Typical applications include sample preparation, product recovery and teaching-lab demonstrations of vacuum filtration. The durable porcelain construction withstands repeated cleaning cycles and routine laboratory handling, making it a practical choice for quality-control, research and educational environments that require reliable Büchner-style filtration hardware.

A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
