Description
DURAN® threaded tube GL 18 is a borosilicate glass 3.3 component designed for attachment to glass apparatus and integration into laboratory glassware systems. These glass threaded tubes feature a standardised GL thread conforming to DIN 12216; the nominal size refers to the outer diameter measured on the thread. They allow secure and straightforward closing as well as opening of glass-to-glass connections and support grease-free working throughout. Intended as glass articles for further processing, the tubes are offered in five sizes, with this GL 18 version providing a practical intermediate diameter for many apparatus builds. Available accessories expand the range of possible configurations. Typical applications include joining onto glass apparatus, incorporation into glass instruments and devices, and construction of custom laboratory setups requiring reliable threaded interfaces. The product is made from DURAN® borosilicate glass 3.3 by Duran/DWK Life Sciences and is supplied as a single piece with a net weight of 0,019 kg. Its standardised thread geometry ensures compatibility with matching GL fittings and seals commonly used in laboratory glass engineering.

Questions about DURAN® Screw Thread Tube, GL
What is this article?
DURAN® Screw Thread Tube, GL 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.
