Description
1-Way stopcock with bent tube connectors NS 14,5 is a precision laboratory glass valve for controlled fluid handling in chemical and analytical apparatus. It combines an NS-PTFE plug with a 2,5 mm bore and bent tube connectors measuring 9 × 100 mm, giving a compact one-way shut-off solution that conforms to DIN 12541. The NS 14,5 ground joint ensures direct compatibility with standard laboratory glassware trains, vacuum lines and distillation setups. Manufactured by Witeg, the stopcock is supplied as a single piece and is intended for reliable flow regulation and isolation in research, quality-control and preparative workflows. The PTFE plug supports smooth rotation and chemical resistance during repeated open–close cycles, while the bent tube outlets simplify routing of tubing or glass connections without additional adapters. With a net weight of 0,047 kg, this robust one-way stopcock integrates cleanly into existing ground-joint systems wherever a durable, DIN-compliant valve with bent connectors is required.

Questions about Stopcock ST 14,5
What is this article?
Stopcock ST 14,5 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.
