Description
2-Way stopcock NS14 with hollow NS glass plug is a compact laboratory glass valve for precise flow control in small-scale apparatus. It features a hollow NS glass plug, bent tube connector and a bore of 1,6 mm, conforming to DIN 12553. The ground joint is specified as NS 14,5, enabling direct coupling to matching ground-joint glassware. Supplied as a single piece with a net weight of 0,047 kg, the stopcock is suited to vacuum lines, liquid transfer and analytical setups where a lightweight two-way shut-off is needed. The hollow-plug design reduces mass while maintaining a reliable seal, and the bent-tube geometry supports neat tubing connections in confined assemblies. From manufacturer Witeg, this component serves synthesis, sample preparation, distillation side-arms and teaching laboratories that depend on interchangeable NS fittings. Its defined bore and DIN-compliant construction support reproducible fluid handling in research, quality-control and educational environments requiring durable glass stopcocks.

Questions about Stopcock, double bore, with hollow plug
What is this article?
Stopcock, double bore, with hollow plug 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.
