Description
Threaded tube GL 45 is a straight glass tube intended for attachment in laboratory glassware systems. It carries an ISO thread to GL 45 and measures 42 x 2,3 x 150 mm (outer diameter × wall thickness × length), conforming to DIN 12216. The generous GL 45 thread and robust wall thickness make this tube well suited for larger vessels, reactors or transfer lines that demand a secure, high-capacity threaded connection. Supplied as one piece with a net weight of 0,1 kg, it serves as a building block for custom apparatus in chemical synthesis, sample preparation and process laboratories. The straight geometry allows straightforward incorporation into existing glass assemblies or new modular constructions. Produced by Witeg, the item belongs to the range of laboratory glass tubing and threaded connectors used wherever interchangeable GL screw fittings are preferred. Matching GL 45 caps, seals and adapters complete the connection, supporting reliable, reusable joints without ground-glass interfaces. Suitable for research, industrial and educational laboratories requiring standardised European glassware components.

Questions about Tube GL 45 Ø: 42 x 2,3 x 150 mm
What is this article?
Tube GL 45 Ø: 42 x 2,3 x 150 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.
