Description
Cap with NS stopcock and straight olive NS 14/23 is a precision laboratory glassware accessory designed for controlled connection and flow regulation on ground-joint apparatus. The component integrates a standard NS 14/23 ground joint with an integral stopcock and a straight olive outlet, enabling secure attachment to compatible flasks, condensers or reaction vessels while permitting precise on/off control of gas or liquid streams. Net weight is 0,048 kg, reflecting a compact yet robust construction suitable for routine laboratory handling. Typical applications include vacuum or inert-gas lines, sampling ports and small-scale reaction setups where a reliable NS interface and simple flow interruption are required. Produced by Witeg, the cap supports modular assembly of laboratory glass systems without additional adapters. Its straightforward geometry facilitates cleaning and repeated use in analytical, synthetic or educational environments that rely on standardised ground-joint connections.

Questions about Suction tube with ST-stopcock and straight olive
What is this article?
Suction tube with ST-stopcock and straight olive 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.
