Description
Separating funnel spherical shape 250 ml NS 29/32 is a precision borosilicate-glass laboratory vessel designed for liquid-liquid extractions and phase separations. The spherical body provides efficient mixing and clear phase-boundary observation, while the ground joint NS 29/32 accepts the supplied NS-PE stopper for secure closure. A removable PTFE stopcock with 2,5 mm bore ensures chemical resistance and smooth, drip-free flow control; the stem length of 100 mm facilitates convenient drainage into receiving vessels. Manufactured from high-quality borosilicate glass, the funnel withstands typical thermal and chemical stresses encountered in organic synthesis, analytical chemistry and preparative work. Supplied in a pack of two pieces from manufacturer Witeg, each unit has a net weight of 0,152 kg. The combination of inert PTFE key, polyethylene stopper and robust glass construction makes this separating funnel suitable for routine solvent extractions, washing steps and fractionation procedures in research and quality-control laboratories. Its standardised joint size allows seamless integration with common laboratory glassware assemblies.

Questions about Separatory funnel globe shaped 250ml ST 29/32
What is this article?
Separatory funnel globe shaped 250ml ST 29/32 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.
