Description
The DURAN® spherical separating funnel in heavy-duty design with a nominal volume of 250 ml is precision laboratory glassware made from borosilicate glass 3.3. Formed as a pear-shaped flask with a drain stopcock at the tip, it is intended for liquid-liquid extraction of two immiscible liquids and can also be applied in purification processes. The denser liquid collects in the lower part of the vessel and is released via the stopcock, while the permanently fired white printed scale enables accurate volume determination. Distinctive attributes include the spherical shape, NS stopcock with NS lid stopper, and robust heavy-duty construction that withstands repeated handling. Supplied as one piece with joint size NS 24/20, this funnel supports reliable phase separation in analytical and preparative workflows. Manufactured by Duran/DWK Life Sciences, it provides durable performance for everyday extraction and cleaning tasks involving immiscible solvent systems in research or industrial laboratories where mechanical strength and clear graduation are essential.
This article is part of 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.
