Description
Separating funnel with valve stopcock and plastic stopper, 250 ml is laboratory glassware for liquid–liquid extraction and phase separation. It is made from high-quality borosilicate glass LBG 3.3 and conforms to DIN / ISO 4800, giving the chemical resistance and thermal stability required for routine analytical and preparative work. The valve stopcock allows controlled drainage of the lower phase while the plastic stopper seals the top during shaking and settling. This 250 ml model has a net weight of 0,440 kg and is supplied as a single piece. Produced by manufacturer Labbox in the GLASSCO range, the funnel is suited to chemistry, biochemistry and quality-control laboratories that perform solvent extractions, washing steps or density-based separations. Standardized construction supports reliable mounting on common stands and clamps. The clear borosilicate body permits ready observation of phase boundaries so that the interface can be cut cleanly. Overall design balances robustness with the fine flow control needed when handling organic solvents and aqueous solutions in everyday laboratory protocols.
This article is part of Separating funnels, in Funnels.

Questions about Separatory funnel, with screw type needle valve and plastic stopper, 250 ml
What is this article?
Separatory funnel, with screw type needle valve and plastic stopper, 250 ml is the article on this page. Luminix Health distributes Labbox 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.
