Description
Separating funnel Squibb 2000 ml NS 29/32 with valve stopcock is a large graduated Squibb-type funnel for high-volume liquid–liquid extraction, phase separation and solvent washing. Fabricated from borosilicate glass 3.3, the vessel delivers chemical resistance and thermal stability needed for preparative laboratory work. The pear-shaped profile aids formation of distinct phase boundaries and complete drainage of the lower layer. Graduation marks on the body allow practical volume estimation during separations. The neck accepts a polyethylene stopper on ground joint NS 29/32, while the outlet is equipped with an Economy valve stopcock of 6 mm bore for controlled release. This 2000 ml funnel from manufacturer Witeg is supplied as a single piece and is intended for preparative organic chemistry, bulk extract work-up, environmental sample processing and larger teaching experiments. Net weight is 0,638 kg. Robust construction and a reliable valve stopcock support repeated use with common laboratory solvents under standard bench conditions.

Questions about Separatory funnels, Squibb, borosilicate
What is this article?
Separatory funnels, Squibb, borosilicate is the article on this page. Luminix Health distributes Witeg 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.
