Description
Filter funnel, conical, 25 ml, Por. 1 is a laboratory glassware item made from borosilicate glass 3.3 for filtration and solid–liquid separation tasks. The conical body has a diameter of 55 mm and is fitted with a VitraPOR® sintered filter plate of 25 mm diameter at porosity grade 1. This configuration suits gravity filtration and related preparative steps where a defined frit porosity is required. Chemically resistant borosilicate 3.3 withstands typical laboratory solvents and thermal stress, giving a durable solution for routine sample work-up. Supplied in packs of 10 pieces from manufacturer ROBU - Stereon, the conical filter funnel supports reproducible separations in research, quality-control and teaching laboratories. Its compact 25 ml capacity is convenient for small-volume filtrations, while the integrated VitraPOR® plate removes the need for loose filter media and simplifies handling within standard glassware protocols.
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.
