Description
Separating funnel with glass stopcock is a conical laboratory vessel for liquid–liquid separations and phase isolation in everyday laboratory practice. This DURAN® model is supplied in conical form with a glass stopcock and a working capacity of 50 ml, suited to small-scale extraction and work-up steps. The unit quantity is 1 pc and the funnel weighs 0,090 kg, so it fits compact bench workflows and limited sample volumes. Conical geometry aids clear observation of phase boundaries and controlled drainage through the stopcock when immiscible layers are separated. DURAN® borosilicate glass construction is specified for this separating funnel, supporting typical chemical laboratory handling within the stated design. From manufacturer Lenz, the item belongs to the separating-funnel group of laboratory glass, vessels and consumables used across synthetic, analytical and teaching laboratories. The glass stopcock enables manual control of outflow during separation procedures. With its 50 ml capacity, this conical separating funnel is intended for general laboratory use where modest volumes of mixed phases need to be divided cleanly and reproducibly.

Questions about Separating funnel, with glass stopcock, DURAN®, conical form, 50 ml, 1 pc
What is this article?
Separating funnel, with glass stopcock, DURAN®, conical form, 50 ml, 1 pc is the article on this page. Luminix Health distributes Lenz 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.
