Description
Separating funnel Squibb 50 ml NS 19/26 with valve stopcock is a graduated Squibb-type laboratory funnel intended for liquid–liquid extractions and clean phase separations. The body is made of borosilicate glass 3.3, offering the chemical resistance and thermal stability required for routine work with aqueous and organic solvents. Clear graduation markings support convenient volume assessment during equilibration and work-up. A polyethylene (PE) stopper seals the NS 19/26 ground joint, while an Economy valve stopcock with a 3 mm bore allows controlled release of the lower phase. This compact 50 ml capacity suits small-scale extractions, sample clean-up and preparative steps where limited volumes still demand reliable separation performance. The pear-shaped Squibb geometry promotes efficient phase disengagement after shaking. Pack size is 2 pieces from manufacturer Witeg, making the item practical for teaching laboratories, analytical benches and quality-control workflows that repeatedly perform solvent extractions. Robust glass construction supports repeated use under standard laboratory conditions without compromising joint integrity or stopcock function.

Questions about Separatory funnel Squibb 50ml ST 19/26
What is this article?
Separatory funnel Squibb 50ml ST 19/26 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.
