Description
DURAN® Expansion Adapter, Socket/Cone NS 29/32 to NS 19/26 is a precision borosilicate glass 3.3 fitting designed to connect laboratory glassware components that have different standard ground-joint sizes. Featuring a socket of NS 29/32 and a cone of NS 19/26, the adapter enables seamless integration of unequal NS parts into a single apparatus. This configuration is widely used when modular glass systems require a transition between larger and intermediate joint diameters while preserving a tight, vacuum-compatible seal. Fabricated from durable borosilicate glass 3.3, the piece offers excellent chemical resistance and thermal stability for everyday laboratory service. It is supplied as one piece with a net weight of 0,037 kg and is ready for immediate incorporation into distillation trains, reaction assemblies or vacuum lines. Manufactured by Duran/DWK Life Sciences under the DURAN® trademark, the adapter delivers reliable dimensional accuracy and sealing performance. It provides a practical, standardised solution for bridging NS 29/32 and NS 19/26 joints without the need for custom glassblowing.

Questions about DURAN® Expansion Adapter , socket/cone
What is this article?
DURAN® Expansion Adapter , socket/cone is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Labware.
A hose connector or adapter joins two lines, or steps one bore down to another. The barb diameter has to match the tube, and the thread has to match the stopcock or the bottle. Most leaks are a mismatch here, not a hole in the tube.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
