Description
Cylindrical separating funnel 50 ml NS 19/26 is an ungraduated laboratory separating funnel intended for liquid–liquid extraction and phase separation on a smaller scale. Made from borosilicate glass 3.3, the vessel provides the chemical resistance and thermal durability expected of quality laboratory glassware. It has a nominal capacity of 50 ml and features a standard ground joint NS 19/26. A solid NS stopcock plug with a 2,5 mm bore allows controlled drainage of the lower phase, while the NS polyethylene stopper seals the top during mixing and settling. The cylindrical body gives a clear view of the solvent interface, supporting accurate separation of organic and aqueous layers in compact work-ups. This model from manufacturer Witeg is supplied as a pack of 2 pieces and has a net weight of 0,08 kg. It is suitable for micro- and small-scale sample preparation, organic synthesis, natural-product isolation and teaching exercises that require reliable ungraduated glass separating funnels. The combination of borosilicate glass 3.3, solid stopcock and PE stopper makes the funnel a practical option for routine extraction procedures in research, quality-control and educational laboratories.

Questions about Separatory funnel Cylinder 50ml ST 19/26
What is this article?
Separatory funnel Cylinder 50ml 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.
