Description
Separating funnel, 50 ml, Squibb, graduated with PTFE key NS 12,5/2,5 mm is a compact laboratory glassware item designed for small-scale liquid-liquid extractions and phase separations. Fabricated from borosilicate glass 3.3, the Squibb pear-shaped body ensures efficient drainage and clear visibility of the liquid interface. The graduated scale allows approximate volume estimation during work-up. Nominal capacity is 0,05 l. A PTFE stopcock with NS 12,5/2,5 mm bore delivers chemical resistance and smooth, grease-free flow control. The top is closed by a PE stopper fitting the NS 19/26 ground joint, providing a secure seal when the funnel is shaken. This separating funnel from manufacturer Rettberg weighs 0,100 kg net and is supplied as one piece. It is well suited to micro-scale organic synthesis, analytical sample preparation, teaching laboratories and any workflow that requires reliable separation of immiscible solvents in limited volumes. The durable borosilicate glass 3.3 construction together with the inert PTFE key supports repeated use with typical laboratory reagents.

Questions about Separatory funnel, 50 ml, Squibb grad., PTFE plug size 12,5/2,5 mm,
What is this article?
Separatory funnel, 50 ml, Squibb grad., PTFE 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.
