Description
DURAN® separating funnel with PTFE stopcock and conical shape is laboratory glassware intended for liquid-liquid extraction and phase separation of immiscible liquids. With a nominal volume of 0,1 l, the vessel has the form of a pointed flask fitted with a drain stopcock at the tip. The denser liquid phase collects in the lower section and can be released cleanly through the PTFE stopcock, while the permanently fired white scale allows accurate volume determination. Manufactured from borosilicate glass 3.3 by Duran/DWK Life Sciences, the funnel combines chemical resistance with thermal stability for routine organic and analytical work. Key advantages include the conical geometry, smooth-operating PTFE stopcock and an easy-to-read graduated scale with line division that remains durable over repeated use. Applications cover phase separation, liquid-liquid extraction and measurement of liquid quantities during purification or sample work-up. The item is supplied as a single unit with a net weight of 0,123 kg and a gross weight of 0,188 kg.
This article is part of Separating funnels, in Funnels.

Questions about DURAN® Separating Funnel with PTFE key, conical shape
What is this article?
DURAN® Separating Funnel with PTFE 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.
