Description
Separating funnel Squibb 500 ml NS 29/32 is an ungraduated laboratory glassware item intended for liquid-liquid extractions and phase separations. Fabricated from borosilicate glass, this Squibb-style funnel has a conical body that supports clear observation of phase boundaries and efficient draining of immiscible layers. It is fitted with an NS 29/32 ground joint, a PE stopper and an NS-PTFE stopcock with a 2,5 mm bore for controlled flow. The 500 ml working volume suits preparative and analytical work in organic chemistry, natural-product isolation and general sample clean-up. This model from manufacturer Witeg combines the chemical resistance and thermal stability expected of quality borosilicate construction with a chemically inert PTFE stopcock. Supplied as a pack of 2 pieces, the funnel is well suited to routine solvent partitioning, extraction sequences and laboratory separations where volume graduations are not required. The ungraduated design keeps the focus on phase clarity while the PE stopper and NS joint ensure secure closure during shaking and settling steps.
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.
