Description
Separating funnel with PTFE stopcock, DURAN®, conical form, is a laboratory glass vessel for liquid–liquid phase separations. This 500 ml conical funnel is equipped with a PTFE stopcock for controlled release of the lower phase after settling. DURAN® glass and the conical body support clear viewing of phase boundaries during extraction, washing and partitioning procedures. The funnel is offered as 1 pc and weighs 0,456 kg, giving a robust yet manageable format for analytical, preparative and teaching laboratories. From manufacturer Lenz, it forms part of the DURAN® conical separating-funnel range used in organic and aqueous work-ups. A 500 ml capacity accommodates larger solvent volumes while remaining practical on a standard bench stand. The conical shape helps collect the denser layer cleanly at the stopcock outlet. Laboratories performing repeated extractions, solvent exchanges or multi-step washes can integrate this funnel into existing clamp setups. PTFE stopcock and DURAN® construction provide a durable, straightforward tool for routine phase-separation workflows.
This article belongs on Separating funnels, in Funnels.

Questions about Separating funnel, with PTFE stopcock, DURAN®, conical form, 500 ml, 1 unit(s)
What is this article?
Separating funnel, with PTFE stopcock, DURAN®, conical form, 500 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.
