Description
Separating funnel with glass stopcock is a DURAN® conical laboratory funnel with 2000 ml capacity for high-volume liquid–liquid extraction and phase separation. The wide conical body assists settling and clear observation of the interface, while the glass stopcock enables measured release of the denser phase. DURAN® construction combines chemical durability with transparency needed when monitoring partition steps in preparative organic chemistry, process development and larger sample work-ups. This funnel from manufacturer Lenz is supplied as one piece with a weight of 1,100 kg and is intended for secure mounting in a suitable stand. Two-litre conical separating funnels are chosen when solvent or extract volumes call for greater working capacity than 500 ml or 1000 ml models. Applications include repeated washing of organic layers, isolation of product-rich phases and teaching demonstrations of extraction technique. The glass stopcock design keeps the outlet path free of elastomer components for many laboratory solvents. Pack size is 1 pc for individual laboratory stocking.
This article belongs on Separating funnels, in Funnels.

Questions about Separating funnel, with glass stopcock, DURAN®, conical form, 2000 ml, 1 unit(s)
What is this article?
Separating funnel, with glass stopcock, DURAN®, conical form, 2000 ml, 1 unit(s) 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.
