Description
DURAN® Filter funnel 4000 ml with porosity 2 is a laboratory filter funnel intended for solid-liquid separation under vacuum. Filtration ranks among the most important separation techniques in the laboratory and is used for the separation or purification of diverse media; filters are therefore selected according to size and porosity for the specific application. This filter funnel incorporates a glass sinter base that acts as the filter medium, so no additional filter paper is required. It is produced from borosilicate glass 3.3, which provides the well-known combination of chemical resistance and high thermal shock resistance, and carries a permanently fired white print for durable identification. Connection to a suction flask is made via a conical rubber seal (GUKO). With a nominal volume of 4 l and a net weight of 2,28 kg, the funnel is supplied as a single piece. Typical applications include qualitative analysis and preparative chemistry, fine filtration, and filtration under reduced pressure. The DURAN® Filter funnel from manufacturer Duran/DWK Life Sciences supports reliable media separation and purification workflows in routine laboratory practice.

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.
