Description
Filter funnel (Hirsch funnel) of 55 mm diameter and 25 ml capacity serves as a specialised glass filtration tool for vacuum-driven separations in the laboratory. It features a porosity 3 sintered disc with 25 mm plate diameter, delivering finer particle retention suitable for more demanding clarification steps. The Hirsch configuration ensures low hold-up volume and straightforward recovery of collected solids. Net weight stands at 0,026 kg. Available as a single unit from manufacturer Witeg, the funnel fits conventional filtration manifolds and can be used alone or in combination with filter papers. Common applications encompass fine precipitate collection, purification of reaction products, analytical sample work-up and quality-control procedures. Its dimensions favour small-scale operations in organic chemistry, pharmaceutical research and educational settings. The robust fritted design supports repeated use with aqueous or organic media under mild vacuum, providing consistent performance for routine laboratory filtration needs.

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.
