Description
Cylindrical separating funnel 500 ml NS 29/32 is an ungraduated laboratory vessel intended for liquid–liquid extractions and phase separations. Constructed from borosilicate glass 3.3, the funnel delivers chemical durability together with good thermal shock resistance for daily laboratory use. It incorporates a solid NS stopcock plug with a 2,5 mm bore and an NS polyethylene stopper matching the NS 29/32 ground joint. The cylindrical body provides a nominal volume of 500 ml and a net weight of 0,289 kg, making it practical to mount on standard stands. Offered by manufacturer Witeg in packs of 2 pieces, this separating funnel is well suited to solvent partitioning, organic-phase washing and sample-preparation workflows in chemistry, biochemistry and analytical laboratories. The ungraduated design keeps the glass wall free of scale markings for clear visual monitoring of interfaces, while the standardised joints guarantee interchangeability with existing glassware. Consistent sealing and smooth flow control through the stopcock support both educational settings and routine research that require robust cylindrical separating funnels of intermediate capacity.
This article is part of Separating funnels, in Funnels.

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