Description
Separating funnel 250 ml NS 29/32 is a cylindrical, ungraduated laboratory glassware item intended for liquid-liquid extractions and phase separations. The 250 ml vessel features an outlet stopcock with PTFE plug NS 12,5/2,5 and an upper ground-joint sleeve NS 29/32 only, closed by an NS-PE stopper. This arrangement permits controlled outflow while the polyethylene stopper provides a secure top seal. The cylindrical, ungraduated body is well suited to applications in which volumes are determined by other means. Offered by manufacturer Witeg, the funnel supports routine organic-chemistry and analytical workflows that require reliable separation of immiscible liquids. Supplied in packs of 2 pc(s), it allows laboratories to maintain ready stocks. Net weight is 0,172 kg, giving a robust yet manageable piece of glassware. Originating from Germany (Baden-Württemberg), the funnel meets typical expectations for laboratory separating funnels used in synthesis, purification and extraction procedures where chemical resistance of the PTFE key and smooth stopcock operation are essential.
This article is part of Separating funnels, in Funnels.

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