Description
Separating funnel, Squibb, with NS PTFE key and poly stopper in Boro 3.3 is intended for liquid–liquid extraction and controlled phase separation in the laboratory. This 250 ml Squibb model features sleeve joint NS 29/32, white inscription and construction according to ISO 4800. The pack contains 2 pieces and is offered by manufacturer Hecht. Borosilicate glass 3.3 provides the chemical resistance and thermal properties required for everyday handling of aqueous and organic solvents. An NS PTFE key controls outflow of the denser phase, while the poly stopper seals the upper opening during mixing and settling. Standard NS joints ensure compatibility with common laboratory glass assemblies used in extraction workflows. The Squibb geometry is a familiar choice for partitioning immiscible liquids in organic synthesis, analytical preparation, preparative work and teaching laboratories. White inscription supports rapid visual identification of capacity and type on crowded benches. Supplied as two units, the set facilitates simultaneous extractions or maintains spare capacity in research and quality-control settings that depend on clean, reproducible phase separations.
This article belongs on 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 Matériel de laboratoire.
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.
