Description
Separating funnel Squibb 250 ml NS 29/32 is an ungraduated laboratory vessel intended for liquid–liquid extractions, solvent washing and phase separations in chemical and analytical workflows. Fabricated from borosilicate glass 3.3, the funnel combines chemical durability with thermal shock resistance suitable for a broad range of laboratory solvents and reagents. Its Squibb pear-shaped profile aids efficient layer separation and smooth drainage of the denser phase. The unit incorporates a solid NS stopcock plug with a 2,5 mm bore for controlled outflow and is closed at the top by a polyethylene (PE) stopper matching the NS 29/32 ground joint. Available as a pack of 2 pieces from manufacturer Witeg, this separating funnel supports organic synthesis, natural-product work, environmental sample preparation and educational laboratories. The ungraduated body emphasises separation reliability over volumetric precision, while the standardised joints allow straightforward integration into common glassware setups. With a net weight of 0,17 kg it remains practical for regular bench-top use.

Questions about Separatory funnel Squibb 250ml ST 29/32
What is this article?
Separatory funnel Squibb 250ml ST 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.
