Description
Separating funnel Squibb 500 ml NS 29/32 is a graduated pear-shaped laboratory vessel intended for liquid-liquid extractions and clean phase separations. Fabricated from borosilicate glass, it offers excellent chemical resistance and optical clarity so that the interface between immiscible layers remains clearly visible. The funnel is fitted with a PTFE stopcock whose 2,5 mm bore permits smooth, controlled drainage without introducing metallic contamination. At the top, an NS 29/32 ground joint accepts the supplied PE stopper, ensuring a secure seal during shaking and equilibration. With a working capacity of 500 ml and clear graduation marks, the design supports medium-scale preparative work in organic synthesis, natural-product isolation and routine analytical laboratories. Produced by manufacturer Witeg, the funnel integrates readily into standard jointed glassware assemblies. Supplied as a pack of 2 pieces, it provides a practical stock item for busy teaching or research environments where reliable, solvent-compatible separation glassware is required on a daily basis.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel Squibb 500ml NS 29/32
What is this article?
Separatory funnel Squibb 500ml NS 29/32 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.
