Description
2-way stopcock with bent tube connectors NS 14,5 and 1,6 mm bore is a precision glass laboratory valve for controlled fluid handling in analytical and preparative work. It combines a solid NS plug with threaded stopcock securing to deliver reliable sealing and smooth operation under repeated use. The bent tube connectors measure 8 × 100 mm, allowing straightforward integration into glass apparatus assemblies. Built to DIN 12553, the stopcock offers standardised dimensions for interchangeability across laboratory glassware systems. With a net weight of 0,064 kg and supplied as a single piece from manufacturer Witeg, the compact unit suits chemistry, biochemistry and general laboratory workflows that require two-way flow control. The NS 14,5 ground-joint interface ensures a secure fit to matching conical joints, while the 1,6 mm bore supports precise metering of liquids and gases. Typical applications include vacuum lines, distillation setups and reaction apparatus where dependable shut-off performance is essential.

Questions about Stopcock double bore bore: 1,6 mm
What is this article?
Stopcock double bore bore: 1,6 mm 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.
