Description
DURAN® adapter in stopper form with socket NS 14/23 and cone NS 24/29 is a compact ground-joint transition piece for connecting laboratory glassware components that have different standard joint sizes. Made from borosilicate glass 3.3, it provides a space-saving reduction from a smaller socket to a larger cone while maintaining a reliable seal. The stopper-shaped design keeps the overall length short, making the piece especially useful where bench or apparatus space is limited. This adapter from manufacturer Duran/DWK Life Sciences is intended for joining two components with differing NS sizes in everyday laboratory assemblies. It supports clean, leak-resistant connections in distillation, reaction and general glassware setups without adding bulk. The unit is supplied as a single piece with a net weight of 0,018 kg, ready for immediate integration into existing NS joint systems. Its robust glass construction ensures chemical resistance and thermal stability typical of borosilicate 3.3 laboratory ware, allowing repeated use under standard laboratory conditions.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about DURAN® Adapter, stopper type
What is this article?
DURAN® Adapter, stopper type is the article on this page. Luminix Health distributes DWK Life Sciences 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.
