Beschrijving
Separating funnel, Squibb type, with NS PTFE key and poly stopper is laboratory glassware made from borosilicate glass 3.3 for liquid–liquid extraction and phase separation. Built to ISO 4800 with white inscription, it offers a 1000 ml working capacity and a ground sleeve joint NS29/32 for secure stopper seating. The Squibb profile aids clear interface formation between immiscible layers, while the PTFE key resists chemical attack and seizure and allows controlled release of the lower phase. A polyethylene stopper closes the neck during shaking and equilibration. Borosilicate 3.3 combines low thermal expansion with broad chemical resistance for repeated use in organic synthesis, sample cleanup and teaching labs. Supplied as a pack of 2 pieces from manufacturer Hecht, this funnel suits preparative extractions, washing steps and solvent partitioning where reliable, reproducible phase separation is required day to day.
This article is part of Separating funnels, in Funnels.

What is this article?
Funnel, separating, Squibb shape with pp stopper, ISO 4800, Boro 3.3, Capacity: is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Separating funnels, inside Funnels, 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.
