Description
Separating funnel 500 ml NS 29/32 is a cylindrical, ungraduated laboratory glassware item designed for liquid-liquid extractions and phase separations. The 500 ml vessel is fitted with an outlet stopcock carrying a PTFE plug NS 12,5/2,5 and an upper ground-joint sleeve NS 29/32 only, completed by an NS-PE stopper. This configuration enables precise control of outflow while the polyethylene stopper seals the top effectively. The cylindrical shape without graduation marks suits procedures in which volume measurement is performed separately. Produced by manufacturer Witeg, the funnel is appropriate for standard organic-chemistry and analytical work requiring dependable separation of immiscible liquids. It is supplied in packs of 2 pc(s), offering practical stocking for busy laboratories. Net weight is 0,334 kg, providing a sturdy yet manageable piece of apparatus. Originating from Germany (Baden-Württemberg), the funnel fulfils customary requirements for laboratory separating funnels used in synthesis, purification and extraction steps where the chemical resistance of the PTFE key and reliable stopcock performance are important.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel 500ml NS 29/32
What is this article?
Separatory funnel 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.
