Description
DURAN® expansion adapter with NS ground joints is a glass laboratory transition piece designed to link apparatus carrying different standard joint sizes. As an expansion type it features a socket NS 24/29 and a cone NS 19/26, enabling secure connection of glassware whose ground joints do not match. Manufactured from borosilicate glass 3.3, the adapter combines chemical resistance with good thermal performance for routine lab work. Transition adapters are available as expansion or reduction forms; this expansion version uses the stated socket-to-cone pairing. Precision-ground NS interfaces deliver a tight closure for distillation trains, reaction setups and modular glass assemblies. Supplied as a single piece with a net weight of 0,029 kg, it supports flexible configuration of multi-joint systems. This DURAN® component from manufacturer Duran/DWK Life Sciences is applied wherever two glass parts must be joined despite differing NS dimensions. The combination of socket 24/29 with cone 19/26 is indicated as not conforming to DIN. Transparent glass permits straightforward visual inspection of the sealed joint during use.
This article is part of Hose connectors, adapters & fittings, in Tubing, hoses & fittings.

Questions about DURAN® Adapter, standard ground joint
What is this article?
DURAN® Adapter, standard ground joint 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.
