Description
DURAN® adapter in stopper form featuring socket NS 24/29 and cone NS 29/32 is a space-efficient transition piece that links two laboratory glass components of unequal standard ground joint size. Produced from borosilicate glass 3.3, it realises a compact reduction from the smaller socket to the larger cone while the stopper-shaped body keeps the overall length and volume to a minimum. This geometry proves especially helpful in crowded setups such as distillation trains, multi-neck flask configurations, reaction assemblies or vacuum lines where conventional reducers would interfere with neighbouring parts. The adapter is supplied as one piece with a net weight of 0,023 kg and provides the chemical resistance together with thermal stability expected of quality laboratory glass. This item from manufacturer Duran/DWK Life Sciences is designed for the straightforward connection of apparatus elements that possess differing Normschliff dimensions. Its compact construction and precise ground-joint interfaces support modular glass systems in research, analytical and preparative laboratories that require reliable, low-profile joints.
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.
