Beschrijving
Büchner funnel 45 mm Ø is a porcelain laboratory filtration funnel intended for vacuum-assisted solid–liquid separations on the bench. Its perforated plate carries holes of 1,0 mm diameter, allowing standard filter papers to rest evenly while filtrate passes cleanly into the receiving flask. Overall height is 67 mm, giving a compact profile that fits common filter-flask assemblies and rubber adapters. Porcelain construction provides mechanical strength and chemical resistance for routine analytical and preparative work. Each funnel from manufacturer Marienfeld is supplied as a single piece, individually packed in a carton for protection during storage and transport. Typical applications include collection of precipitates after crystallisation, isolation of reaction products in organic synthesis, and sample clean-up in pharmaceutical or quality-control laboratories. The 45 mm plate diameter matches correspondingly sized filter discs, supporting efficient cake formation and washing steps under reduced pressure. This classic Büchner design remains a standard tool wherever reliable laboratory filtration of solids from mother liquors is required.

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.
