Description
2-way stopcock with bent tube connectors NS 14,5 and 1,6 mm bore is a precision glass laboratory valve for reliable flow control in chemical and analytical setups. It features an NS-PTFE plug together with bent tube connectors and a threaded stopcock lock, manufactured in accordance with DIN 12553. The ground joint size is NS 14,5 with connector dimensions of 8 × 100 mm, giving a compact yet robust geometry suited to standard laboratory glassware assemblies. Supplied as a single piece with a net weight of 0,06 kg, the stopcock is intended for routine isolation and metering of liquids or gases in research, quality-control and teaching laboratories. The PTFE plug ensures smooth operation and chemical resistance against a wide range of reagents, while the bent-tube configuration facilitates space-saving installation in crowded apparatus. This component from manufacturer Witeg integrates readily into existing conical-joint systems and supports reproducible handling of process streams without the need for additional adapters. Ideal for vacuum lines, distillation trains and general fluid-routing applications where a durable two-way valve with defined bore is required.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

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