Description
The DURAN® separating funnel in spherical heavy-duty design with a nominal volume of 5 l is intended for liquid-liquid extraction and phase separation of two immiscible liquids. Its pear-flask geometry with a bottom drain stopcock lets the higher-density liquid settle and be drawn off cleanly while the lighter phase remains above. An on-vessel printed scale enables precise volume reading throughout the separation step. Fabricated from borosilicate glass 3.3, this funnel from manufacturer Duran/DWK Life Sciences delivers the chemical durability and mechanical stability expected in preparative and purification workflows. Heavy-duty execution includes an NS stopcock and matching NS stopper; the joint size is NS 45/40. The white graduation is fired into the glass, remaining permanently legible under repeated use and cleaning. Applications cover phase separation, liquid-liquid extraction and associated cleaning procedures that require reliable drainage and clear observation of the phase boundary. The spherical body supports efficient mixing and straightforward visual monitoring of layer formation.
This article belongs on Separating funnels, in Funnels.

Questions about DURAN® Separating Funnel spherical, heavy-duty version
What is this article?
DURAN® Separating Funnel spherical, heavy-duty version 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.
