Description
1-Way stopcock with bent tube connectors NS 24 is a laboratory glass stopcock for controlled one-way flow in chemical apparatus, vacuum lines and general fluid-handling setups. It features an NS 24 ground joint, bent tube connectors and an 8 mm bore that supports secure tubing attachment and practical throughput for many standard laboratory tasks. An NS-PTFE plug delivers a chemically resistant, low-friction sealing surface for smooth operation and dependable shut-off. The design conforms to DIN 12541, ensuring dimensional interchangeability with other standardized glassware components. Supplied as a single piece with a net weight of 0,138 kg, the stopcock is well suited to distillation assemblies, gas-routing manifolds and benchtop systems where a simple one-path valve is preferred. Bent connectors help ease tubing layout and reduce mechanical stress in crowded fume hoods. This unit from manufacturer Witeg is intended for everyday use in research, analytical and teaching laboratories that require durable, interchangeable one-way stopcocks without the complexity of multi-way configurations.

Questions about stopcock ST 24
What is this article?
stopcock ST 24 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.
