Description
DURAN® Expansion Adapter, Socket/Cone NS 29/32 to NS 14/23 is a borosilicate glass 3.3 connecting piece that joins two glass components of different standard ground-joint sizes. The adapter carries a socket of NS 29/32 and a cone of NS 14/23, allowing dissimilar NS parts to be combined into a single leak-tight assembly. Such adapters are essential when modular glass apparatus must accommodate varying joint diameters without custom fabrication. The component is manufactured from chemically resistant borosilicate glass 3.3, ensuring thermal stability and durability under typical laboratory conditions. Supplied as a single piece with a net weight of 0,034 kg, it integrates directly into distillation, reaction or vacuum setups. Produced by manufacturer Duran/DWK Life Sciences under the DURAN® brand, the expansion adapter provides a straightforward solution for linking larger and smaller ground-joint elements while maintaining the precision and sealing performance expected of DURAN® glassware. It is intended for use wherever standardised NS connections of unequal size must be bridged reliably.

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.
