Description
Hollow replacement plug NS 24 is a Type N laboratory stopcock plug designed for standardised NS 24 ground joint interfaces. This hollow plug is supplied without a threaded stopcock lock, provides an 8 mm bore and meets DIN 12541 requirements. Packaged as one piece with a net weight of 0,031 kg, it functions as a ready replacement for damaged or worn plugs in laboratory stopcock assemblies. The hollow form reduces component mass while retaining the seating geometry needed for secure fit in matching glassware. From manufacturer Witeg, the plug is intended for maintenance of stopcocks used in fluid transfer, reaction setups, vacuum lines and everyday chemical glassware. The NS 24 joint size matches widely used European laboratory standards, supporting interchangeability across flasks, adapters and stopcock barrels. Facilities that standardise on DIN 12541 fittings can reinstate reliable flow control through the 8 mm bore by fitting this Type N hollow plug. It is well suited to research, analytical and quality-control laboratories that service glass stopcock systems and prefer a simple hollow design without threaded lock hardware.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about ST-seperate plug hollow ST 24
What is this article?
ST-seperate plug hollow ST 24 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
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.
