Description
Separating funnel in squibb form is a graduated 250 ml laboratory vessel equipped with a PTFE plug 14.5 and ground joint 29/32 for medium-scale liquid–liquid separations. The pear-shaped body supports efficient settling and clear observation of the phase interface, while graduation marks assist volume tracking during extraction, washing and transfer steps. The PTFE plug offers chemically resistant, controllable shut-off for draining the lower layer with minimal sticking. Supplied by manufacturer Lenz as a two-piece pack, the funnel suits parallel work or backup use on the bench. Joint 29/32 matches larger standard glassware assemblies common in preparative organic chemistry. With 250 ml capacity it is well matched to typical reaction work-ups, solvent partitioning and sample clean-up in research, process development and teaching laboratories. Select this graduated squibb separating funnel when PTFE plug performance and a robust joint size are required for routine aqueous–organic separations.
This article belongs on Separating funnels, in Funnels.

Questions about Separating funnel, squibb-form, graduat., PTFE-plug 14.5, joint 29/32, 250 ml
What is this article?
Separating funnel, squibb-form, graduat., PTFE-plug 14.5, joint 29/32, 250 ml 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.
