Description
Separating funnel 1000 ml NS 29/32 is a Gilson-type laboratory glassware item designed for larger-scale liquid-liquid extractions and phase separations. Constructed from borosilicate glass, the ungraduated funnel provides a 1000 ml capacity and is equipped with a standard ground joint NS 29/32. It features an NS-PTFE stopcock with a 4 mm bore for controlled drainage of the lower phase and is closed by a polyethylene stopper that ensures a tight, chemically resistant seal. The robust glass body offers excellent resistance to thermal shock and a broad range of organic solvents and aqueous reagents commonly encountered in synthetic and analytical chemistry. Produced by manufacturer Witeg, the funnel combines the durability of borosilicate glass with the smooth, inert operation of a PTFE stopcock. Net weight is 0,434 kg. The 1000 ml volume makes it particularly suitable for preparative extractions, natural-product isolation and quality-control procedures that require larger sample volumes while maintaining clear phase-boundary observation. Supplied as a single piece, this separating funnel is ready for immediate integration into research, teaching or industrial laboratory workflows that demand reliable, ungraduated glassware of this capacity and joint specification.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel 1000 ml ST 29/32
What is this article?
Separatory funnel 1000 ml 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.
