Description
Separating funnel, 2000 ml, Squibb, ungraduated with PTFE key NS 18,8/6 mm is a laboratory glassware vessel for liquid-liquid extraction and phase separation. The body is manufactured from borosilicate glass 3.3 in the classic Squibb pear shape that promotes complete drainage of the denser phase and clear observation of the interface. Nominal volume is 2 l; the ungraduated wall leaves the phase boundary unobstructed. Flow is controlled by a PTFE stopcock with NS 18,8/6 mm bore, providing chemical resistance and grease-free operation. The upper opening accepts a PE stopper on the NS 29/32 ground joint for secure closure during shaking. This separating funnel from manufacturer Rettberg has a net weight of 0,705 kg and is supplied as a single piece. It is suited to preparative organic chemistry, natural-product isolation, solvent partitioning and routine analytical sample work-up where reliable separation of immiscible liquids is required. The combination of borosilicate glass 3.3 and PTFE components supports use with a broad range of common laboratory solvents and reagents.

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.
