Beschrijving
Separating funnel 500 ml is a conical laboratory funnel manufactured from borosilicate glass 3.3 in accordance with DIN ISO 4800. This ungraduated model is fitted with a stopcock carrying an NS PTFE plug, a stopcock joint NS 18,8 and a bore of 4,0 mm, together with a PE stopper NS 29/32. The nominal volume of 0,5 l suits medium-scale liquid-liquid extractions, phase separations and washing steps in organic synthesis, analytical chemistry and preparative laboratory work. Its conical geometry aids complete drainage and clear observation of phase boundaries during equilibration and separation. The PTFE plug provides smooth, chemically resistant shut-off control for precise release of lower layers. Supplied as a single piece from manufacturer Marienfeld, the funnel integrates readily into standard laboratory glassware sets for routine extraction and isolation procedures. Borosilicate glass 3.3 construction follows the material specification of the cited standard, supporting everyday use in research, teaching and quality-control environments where reliable separating funnels are required.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnels 500 ml,
What is this article?
Separatory funnels 500 ml, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Scheitrechters, inside Trechters, in Labmateriaal.
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.
