Description
2-way stopcock NS 14 capillary connectors bore 1,6 mm is a precision glass valve designed for controlled flow in laboratory vacuum and gas lines. It incorporates a solid NS plug, capillary side arms and a threaded stopcock lock according to DIN 12553. The nominal joint size is NS 14,5 with a bore of 1,6 mm; the capillary connectors measure 8 × 100 mm, providing a compact yet robust connection geometry. Net weight is 0,072 kg. Manufactured by Witeg, the stopcock is intended for use in analytical assemblies, distillation set-ups and general laboratory glassware systems where reliable two-way switching and leak-tight sealing are required. The solid plug and threaded retention ensure secure operation under typical laboratory pressure differentials, while the capillary outlets facilitate direct coupling to narrow-bore tubing or further glass components. Supplied as a single unit, it integrates readily into existing NS-joint apparatus.

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