Description
Büchner funnel 70 mm Ø is a porcelain laboratory filtration funnel for vacuum-assisted separation of solids from liquids. Its perforated plate is fitted with holes of 1,0 mm diameter, enabling filter paper to lie flat while filtrate drains into the receiving vessel. Porcelain construction delivers the chemical resistance and mechanical stability needed for repeated use in analytical and preparative settings. Each funnel from manufacturer Marienfeld is supplied singly and packed in its own carton for secure handling and storage. The 70 mm plate diameter suits correspondingly larger filter papers and supports higher solid loadings than smaller Büchner formats. Typical laboratory applications include recovery of precipitates, isolation of crystallisation products, and sample preparation in organic chemistry, pharmaceutical development, and quality-control laboratories. Under reduced pressure the funnel promotes efficient cake washing and clear filtrate collection. This classic porcelain Büchner design remains a dependable choice for routine solid–liquid filtration on the laboratory bench.
This article is part of Büchner & filter funnels, in Funnels.

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.
