Description
3-Way stopcock PTFE thread NS 24 is a precision laboratory glassware component with a T-bore for controlled multi-directional fluid routing in chemical and analytical setups. It features an NS-PTFE plug together with a threaded stopcock lock that secures the plug against unintended movement during use. Bent tube connections measure 13 × 120 mm and the bore diameter is 6,3 mm; the design follows DIN 12554 for standardized interchangeability with common ground-joint apparatus. Available from manufacturer Witeg as a single piece with a net weight of 0,151 kg, the stopcock integrates readily into glass assemblies used for synthesis, distillation, fractionation and sample transfer. The NS 24 joint size matches widely employed laboratory glassware systems, while the PTFE plug provides an inert sealing surface compatible with many solvents and reagents. This three-way valve is suited to research, quality-control and process laboratories that require durable flow control, reliable sealing and a threaded locking mechanism for everyday bench and apparatus work.

Questions about Stopcock, three-way, ST 24
What is this article?
Stopcock, three-way, 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.
