Description
DURAN® separating funnel with glass stopcock, conical shape, 50 ml is a laboratory glassware item formed like a pointed flask with a drain stopcock at the tip for controlled release of the lower phase. It is intended for liquid-liquid extraction of two immiscible liquids and related purification steps: the denser liquid collects in the lower section and can be drained through the stopcock while the permanently fired white graduation scale supports accurate volume determination. The conical geometry is particularly well suited to clear phase separation. Made from borosilicate glass 3.3, the funnel combines chemical resistance with thermal stability for everyday laboratory use. This single-piece unit from manufacturer Duran/DWK Life Sciences features a glass stopcock and a durable, enamel-fired white print that remains legible over long service life. Typical applications include phase separation and liquid-liquid extraction in analytical and preparative chemistry workflows where reliable volumetric control and inert glass contact surfaces are required.
This article is part of Separating funnels, in Funnels.

Questions about DURAN® Separating Funnel with glass key, conical shape
What is this article?
DURAN® Separating Funnel with glass key, conical shape is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Separating funnels, inside Funnels, in Labware.
A separating funnel lets two immiscible liquids settle into layers and then runs off the lower one through a stopcock. The shape, Squibb or pear, changes how sharp the interface is as the last millilitres leave. The stopper and the stopcock are both needed.
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.
