Description
Separating funnel Squibb 100 ml NS 19/26 with valve stopcock is a graduated Squibb-style glass funnel for liquid–liquid extraction and phase separation in the laboratory. Fabricated from borosilicate glass 3.3, it combines good chemical durability with thermal stability for everyday solvent work. Graduation marks on the body aid volume reading during extraction and work-up sequences. The NS 19/26 ground joint is closed with a polyethylene (PE) stopper, and an Economy valve stopcock featuring a 3 mm bore provides precise drainage of the denser phase. The 100 ml working volume is well suited to medium-scale sample preparation, clean-up and partitioning steps in chemistry, biochemistry and quality-control settings. Classic Squibb pear geometry assists rapid phase boundary formation after mixing. Supplied as a pack of 2 pieces from manufacturer Witeg, the funnel integrates easily into standard extraction protocols. Reliable joint sealing and smooth stopcock operation support repeated shaking and settling cycles while maintaining clear visibility of the interface throughout the procedure.

Questions about Separatory funnel Squibb 100ml ST 19/26
What is this article?
Separatory funnel Squibb 100ml ST 19/26 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.
