Description
Separating funnel, 50 ml, Squibb, ungraduated is a classic laboratory funnel for liquid-liquid extractions and phase separations. Manufactured from borosilicate glass 3.3, it features a solid glass key stopcock with NS 12,5/2,5 mm bore and a PE stopper fitting the NS 19/26 joint. The Squibb shape and ungraduated body provide a simple, robust design well suited to small-scale organic chemistry, sample clean-up and analytical work. With a nominal volume of 50 ml (0,05 l), the funnel allows precise draining of the lower phase under controlled stopcock operation. This single-piece item from manufacturer Rettberg combines the thermal and chemical resistance of borosilicate glass 3.3 with reliable glass-key performance. It is intended for research, teaching and quality-control laboratories that prefer traditional Squibb geometry for efficient separation of immiscible liquids. The PE stopper and standard ground joint ensure secure closure during shaking and equilibration steps.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel, 50 ml, Squibb non-grad., glass plug size 12,5/2,5 mm,
What is this article?
Separatory funnel, 50 ml, Squibb non-grad., glass plug size 12,5/2,5 mm, is the article on this page. Luminix Health distributes Rettberg 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.
