Description
DURAN® Separating Funnel with glass stopcock and conical shape is a laboratory glassware item intended for liquid-liquid extraction of two immiscible liquids as well as related purification steps. Formed like a pear-shaped flask with a drain stopcock at the tip, it allows the denser liquid phase to settle in the lower section and be released in a controlled manner. The conical geometry supports clean phase separation, while the permanently fired white printed scale permits accurate volume reading during use. Made from borosilicate glass 3.3, the 2000 ml funnel combines chemical resistance with good thermal performance for everyday laboratory work. Supplied as a single piece from manufacturer Duran/DWK Life Sciences, it is particularly suitable for phase separation and liquid-liquid extraction in analytical and preparative chemistry. The integrated glass stopcock provides reliable flow control when draining the lower layer. Durable construction and clear graduation markings make this separating funnel a practical tool for routine separation tasks in research, teaching and quality-control laboratories.

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.
