Description
Separating funnel Walter 500 ml NS 29/32 is an ungraduated laboratory vessel designed for efficient liquid-liquid extraction and separation of immiscible phases. Fabricated from borosilicate glass 3.3, it features an NS 29/32 ground joint closed by a polyethylene (PE) stopper and an NS-PTFE stopcock with a 2,5 mm bore for precise drainage control. The 500 ml capacity accommodates larger sample volumes typical of preparative organic chemistry, natural-product work-ups and environmental sample processing while remaining free of graduation marks. Chemical resistance of the glass body combined with the inert PTFE plug ensures compatibility with a wide range of organic solvents and aqueous reagents. This Walter-pattern funnel from manufacturer Witeg mounts directly onto standard NS jointware and supports clear visual observation of phase boundaries. Supplied as a two-piece pack, the item is ready for immediate deployment in research, quality-control or teaching laboratories that require dependable, leak-resistant phase separation under routine bench conditions.
This article is part of Separating funnels, in Funnels.

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