Description
Büchner funnel made of porcelain 70 mm Ø is a classic laboratory filtration funnel intended for vacuum-assisted solid-liquid separations. The porcelain body incorporates a perforated plate that supports filter paper during suction filtration, a technique widely applied in chemical synthesis, sample preparation, precipitation work-ups and analytical routines. Porcelain offers good chemical resistance and mechanical robustness for everyday laboratory handling. With a working diameter of 70 mm, the funnel is sized for medium-scale filtrations commonly performed in research, teaching and quality-control laboratories. Supplied as a single piece from manufacturer Hecht, it integrates readily with standard filter flasks, rubber adapters and vacuum sources. The traditional Büchner geometry promotes even distribution of the filter cake and efficient solvent removal. This porcelain funnel remains a reliable, reusable component of any well-equipped filtration workstation where consistent results and chemical durability are required.
This article is part of Büchner & filter funnels, in Funnels.

A Büchner funnel is a perforated porcelain or plastic plate used with a rubber cone and vacuum to pull liquid through a filter paper. A filter funnel is the glass cone that holds a folded paper under gravity. The plate diameter decides the paper size.
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.
