Description
Separating funnel Squibb 2000 ml, graduated, with PTFE key NS 18,8/6 mm is a classic laboratory glassware item for liquid-liquid extractions and phase separations. Manufactured from borosilicate glass 3.3, it combines chemical resistance with thermal stability for routine organic and analytical work. The Squibb pear-shaped body carries clear graduation marks that support volume estimation during separations, while the PTFE stopcock with NS 18,8/6 mm bore provides smooth, chemically inert flow control. A PE stopper fitting the NS 29/32 joint seals the top securely. This model from manufacturer Rettberg has a nominal volume of 2 l and a net weight of 0,693 kg, making it practical for preparative chemistry, solvent partitioning and teaching laboratories. The single-piece unit integrates readily into standard ground-joint assemblies and withstands typical laboratory solvents and mild thermal stress. Graduated Squibb geometry aids clean phase cuts and reduces hold-up compared with cylindrical designs, supporting efficient work-up of reaction mixtures and extractive isolation steps.

Questions about Separatory funnel, 2000 ml, Squibb, non-grad., PTFE plug size 18,8/6 mm,
What is this article?
Separatory funnel, 2000 ml, Squibb, non-grad., PTFE plug size 18,8/6 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.
