Description
2-Way stopcock NS24 with bent tube connectors is a precision laboratory glass valve for controlled flow in chemical and analytical apparatus. It combines an NS plug with bent tube connectors, a 6,3 mm bore and a threaded stopcock lock that keeps the plug securely seated during use. The ground joint is NS 24 with overall dimensions of 10 × 110 mm, allowing straightforward integration into standard ground-joint glassware trains. Supplied as a single piece with a net weight of 0,123 kg, the stopcock is well suited to vacuum lines, liquid transfer and general fluid handling where reliable two-way shut-off is required. The bent-tube geometry supports compact tubing runs while preserving chemical resistance typical of laboratory glass. From manufacturer Witeg, this component serves synthesis, distillation, sample preparation and teaching laboratories that rely on interchangeable NS fittings. Its robust construction and defined bore support reproducible flow control across routine research and quality-control workflows.

Questions about Stopcock, double bore, ST 24
What is this article?
Stopcock, double bore, ST 24 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
