Description
Separating funnels, cylindrical, 500 ml are graduated glass vessels equipped with a PTFE plug for liquid–liquid separation tasks. The cylindrical form gives a clear view of phase boundaries, which is useful when partitioning solvents, washing organic layers, or isolating product fractions during work-up. Graduation supports approximate volume orientation while the PTFE plug offers a chemically resistant closure for controlled draining of the lower phase. These funnels are intended for everyday laboratory extraction and purification steps in research, teaching, and quality-control settings. Offered as two units per pack from manufacturer Lenz, the set suits benches that need matched glassware for parallel separations. Individual weight is 0,624 kg, consistent with durable laboratory glass construction for repeated handling. The combination of cylindrical geometry, graduation, and PTFE stopcock makes the funnels a practical choice for medium-scale solvent extractions and related wet-chemistry operations that require reliable phase separation.
This article is part of Separating funnels, in Funnels.

Questions about Separating funnels, cylindrical, 500 ml, graduated wiith PTFE plug, 2 unit(s)
What is this article?
Separating funnels, cylindrical, 500 ml, graduated wiith PTFE plug, 2 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
