Description
1-Way stopcock capillary NS 14,5 bore 2,5 mm is a ground laboratory stopcock built for single-way control of liquids and gases in glass apparatus. It features a solid NS plug, capillary ends measuring 9 x 100 mm and a bore of 2,5 mm, offering a practical balance between flow capacity and compact connection geometry. The NS 14,5 ground joint and DIN 12541 specification support compatibility with standard laboratory glassware, while the ground finish aids sealing performance in routine analytical and preparative setups. Capillary approaches suit fine lines where controlled opening and shut-off are required with limited dead volume. Delivered as a single piece with a net weight of 0,052 kg, the component from manufacturer Witeg originates from Germany and fits valve, conical-stopcock and shut-off applications across research and quality-control laboratories. Its solid-plug capillary construction provides a durable option for everyday fluid routing where an NS 14,5 joint and 2,5 mm bore are specified.

Questions about Stopcock ST 14/2,5
What is this article?
Stopcock ST 14/2,5 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.
