Description
Threaded tube GL18 with tube diameter 16 x 1,8 x 110 mm is a straight laboratory glass connector fitted with a GL 18 ISO thread. Manufactured in accordance with DIN 12216, it provides a standardised threaded interface for screw-cap closures and modular glass assemblies. The tube measures 16 mm outer diameter, 1,8 mm wall thickness and 110 mm length, offering a slightly larger bore and longer reach than smaller GL sizes for medium-flow or apparatus-linking applications. It is intended for permanent or semi-permanent set-up of reaction vessels, transfer lines and distillation accessories where secure, reusable GL joints are required. Supplied as a single piece from manufacturer Witeg, the component integrates readily into existing GL-thread glassware systems. With a net weight of approximately 0,018 kg it remains easy to handle while delivering the mechanical stability expected of laboratory-grade threaded tubing.

Questions about Tubes straight GL 18
What is this article?
Tubes straight GL 18 is the article on this page. Luminix Health distributes Witeg 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.
