Description
Squibb separating funnel 2000 ml NS 29/32 with NS-PTFE stopcock is an ungraduated borosilicate glass vessel intended for liquid-liquid extractions and phase separations. The classic pear-shaped Squibb form, fitted with a polyethylene stopper and a stopcock bore of 6,3 mm, supports clear observation of phase boundaries and controlled drainage of the lower layer. With a working capacity of 2000 ml this funnel suits preparative organic chemistry, solvent partitioning, natural-product isolation and routine sample work-up. Supplied as a single piece with a net weight of 0,75 kg, the unit from manufacturer Witeg connects directly to standard NS 29/32 ground-joint assemblies and common laboratory stands. Its ungraduated body emphasises chemical resistance, thermal stability and mechanical durability rather than volumetric markings, making it a practical choice for repeated use in research, quality-control and teaching laboratories that handle diverse aqueous and organic media.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel 2000 ml ST 29 ST-PTFE-stopcock
What is this article?
Separatory funnel 2000 ml ST 29 ST-PTFE-stopcock is the article on this page. Luminix Health distributes Witeg 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.
