Description
DURAN® Filter funnel 1000 ml with porosity 4 is a specialised laboratory glassware item intended for vacuum-assisted solid-liquid separation and media purification. Filtration ranks among the most important separation techniques in the laboratory, and this filter funnel is selected according to the required size and porosity for the application. It incorporates a glass sinter base that functions as the permanent filter medium, removing the necessity for separate filter paper. The unit has a nominal volume of 1 l and is produced from borosilicate glass 3.3, a material valued for its chemical resistance and high resistance to thermal shock. A permanently fired white print ensures durable marking. The funnel connects to a suction flask by means of a conical rubber gasket (GUKO). Applications include qualitative analysis and preparative chemistry, fine filtration, and filtration under reduced pressure. This DURAN® filter funnel from manufacturer Duran/DWK Life Sciences delivers consistent performance for routine and specialised laboratory filtration workflows. Its robust construction supports repeated use in demanding chemical environments while maintaining filtration integrity.
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.
