Description
DURAN® filter funnel 500 ml with porosity 4 is a specialised laboratory glassware item used for solid-liquid separation by means of vacuum. Filtration remains one of the most important separation methods in the laboratory environment for the purification of different media, and this filter funnel is selected according to size and porosity for the specific application. It possesses a glass sinter bottom that serves as the filter medium and requires no further filter paper. The unit has a nominal volume of 0,5 l and is produced from borosilicate glass 3.3, which provides proven chemical resistance together with high resistance to thermal shock. Connection to the suction flask is achieved over a conical rubber seal (GUKO). This filter funnel from manufacturer Duran/DWK Life Sciences features a permanently fired and therefore durable white print. Typical applications include qualitative analysis and preparative chemistry, fine filtration, filtration under reduced pressure and general filtering tasks.

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.
