Description
Separating funnel 500 ml conical shape NS PTFE stopcock is an ungraduated borosilicate glass vessel used for liquid-liquid separations and extraction procedures in the laboratory. The conical body, made of borosilicate glass, combines chemical resistance with clear visualisation of phase boundaries. It is equipped with an NS-PTFE stopcock of 4 mm bore that delivers controlled flow and an NS-PE stopper fitting the NS 29/32 joint for secure sealing during mixing and settling. The 500 ml capacity accommodates larger-scale sample work-ups, solvent extractions and preparative chemistry applications. Supplied in packs of 2 pieces with a net weight of 0,243 kg, the funnel allows complete drainage and convenient handling. From manufacturer Witeg, this borosilicate separating funnel provides a robust, solvent-compatible option for research and teaching laboratories that require reliable PTFE stopcock performance without graduation marks on the body.

Questions about Separatory funnel 500 ml conical ST-PTFE-stopcock
What is this article?
Separatory funnel 500 ml conical ST-PTFE-stopcock is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Separating funnels, inside Funnels, in Matériel de laboratoire.
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.
