Description
DURAN® filter funnel 125 ml with porosity 1 is a laboratory filtration device designed for solid-liquid separation under vacuum. It features an integrated glass sinter base that acts as the filter medium, so no additional filter paper is required. The funnel is joined to a suction flask by means of a conical rubber seal (GUKO), allowing reliable operation at reduced pressure. Made from borosilicate glass 3.3, the article combines high chemical resistance with excellent thermal shock resistance—properties characteristic of DURAN® glassware from manufacturer Duran/DWK Life Sciences. A permanently fired white print remains legible throughout repeated use. With a nominal volume of 125 ml this filter funnel is well suited to qualitative analysis, preparative chemistry and fine filtration work. Its robust construction supports routine laboratory handling while maintaining dimensional stability. The design is intended for purification and separation of diverse media whenever vacuum-assisted filtration is needed in research or quality-control environments.
This article is part of Büchner & filter funnels, in Funnels.

Questions about DURAN® Filter Funnel
What is this article?
DURAN® Filter Funnel is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Büchner & filter funnels, inside Funnels, in Labware.
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.
