Description
Threaded tube GL 25 is a straight glass tube designed for attachment in laboratory glassware assemblies. It features an ISO thread to GL 25 and external dimensions of 22 x 1,8 x 110 mm (outer diameter × wall thickness × length), manufactured in accordance with DIN 12216. This component is intended for building custom glass apparatus where a reliable threaded connection is required for secure coupling of flasks, condensers or other laboratory elements. Supplied as a single piece with a net weight of 0,025 kg, the tube offers a compact format suitable for compact set-ups and modular glass systems. The straight geometry facilitates straightforward incorporation into existing lines or new constructions. Produced by Witeg, the item belongs to the category of laboratory glass tubing and threaded connectors used in chemical, analytical and preparative work. Its defined GL 25 thread and standardised dimensions support interchangeability with matching GL screw caps, connectors and seals commonly employed in European laboratory practice. Ideal for research, teaching and industrial laboratories that require precise, reusable glass connections without ground joints.

Questions about Tube GL 25 Ø: 22 x 1,8 x 110 mm
What is this article?
Tube GL 25 Ø: 22 x 1,8 x 110 mm 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.
