Description
Büchner funnel for filter paper Ø 90 mm with dimensional specification d1xd2xd3xh1xh2xV/ml 97/70/2 mm-40/71 and 240 ml capacity is a classic laboratory filtration funnel intended for vacuum-assisted solid-liquid separations. The funnel accepts standard 90 mm filter paper and presents the geometric ratios 97 mm / 70 mm / 2 mm for the successive diameters together with heights of 40 mm and 71 mm, yielding a working volume of 240 ml. These proportions ensure stable seating of the filter medium and efficient filtrate flow into the receiving flask. Supplied as a single piece from manufacturer Hecht, the funnel belongs to the standard labware range used for routine sample preparation, precipitate collection and washing steps. Its clearly defined dimensional series allows direct matching to common filter-paper sizes and vacuum filtration assemblies, supporting reproducible work in analytical, preparative and teaching laboratories. The compact 240 ml volume suits moderate sample loads while remaining easy to handle and clean. Overall geometry and paper diameter are taken directly from the manufacturer data, guaranteeing interchangeability with existing Hecht Büchner systems.
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.
