Description
Stopper NS stopcock 19/26 RD14 with screw cap and olive is a complete laboratory glassware fitting that combines an NS 19/26 stopper, NS stopcock, bent RD 14 threaded connection, screw cap and olive. The design allows secure hose attachment via the olive while the RD 14 thread and screw cap provide a robust, sealed interface. Integrated stopcock and bent geometry support controlled, directional transfer of gases or liquids in ground-joint apparatus. This single-piece unit from manufacturer Witeg has a net weight of 0,038 kg and is supplied ready for use on compatible NS 19/26 systems. It is suited to laboratory setups that require a stopper with stopcock plus threaded hose coupling rather than a plain olive alone. The complete assembly with screw cap and olive simplifies connection of flexible tubing to reaction, distillation or vacuum glassware. Originating from Germany (Baden-Württemberg), the component fits standard chemical laboratory workflows that depend on interchangeable NS joints and reliable screw-coupled hose connections at the NS 19/26 size.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SUCTION TUBE, WITH ST- STOPCOCK, BENT,
What is this article?
SUCTION TUBE, WITH ST- STOPCOCK, BENT, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
