Description
1-way stopcock with glass handle NS 14,5 is a Type N laboratory stopcock fitted with a hollow NS plug and glass handle for manual control of liquid and gas flow in glass apparatus. Conforming to DIN 12541, it provides a standard ground-joint connection at NS 14,5 with a bore diameter of 2,5 mm. The hollow plug rotates smoothly in the barrel, while the glass handle gives a secure grip for opening and closing. A threaded stopcock retainer holds the plug firmly in place and helps prevent accidental dislodgement during use. Supplied as a single piece with a net weight of 0,038 kg, this valve is intended for integration into reaction setups, distillation trains and general laboratory glassware that require a one-path shut-off or metering function. The NS 14,5 joint size matches common laboratory glass connections, allowing direct incorporation without adapters. This component from manufacturer Witeg belongs to a proven range of conical stopcocks for chemical and analytical laboratories where DIN-compliant dimensions and reliable mechanical locking are required. The 2,5 mm bore supports controlled passage of media in routine laboratory procedures.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

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