Description
Threaded tube GL 60 constricted is a laboratory glass component intended for attachment in modular apparatus, featuring a constricted profile with ISO thread according to DIN 12216. The tube measures 75 x 130 x 2,2 mm and provides a standardised GL 60 interface for secure connection to compatible vessels, caps or adapters. Its constricted form supports reliable joining in distillation, reaction or transfer assemblies commonly required in chemical and analytical work. Supplied as a single piece, this threaded tube from manufacturer Witeg integrates readily into custom glassware configurations where mechanical stability and leak-tight sealing are essential. The ISO thread profile ensures broad compatibility with existing GL 60 laboratory fittings used across research and quality-control environments. Precise dimensional control of the 2,2 mm wall contributes to consistent performance during repeated assembly cycles. Technicians employ such tubes when building or modifying glass systems that demand standardised threaded ports. The component is suitable for routine laboratory operations involving a variety of solvents and reagents when chemical compatibility is verified. Overall it offers a practical, standards-compliant solution for extending or adapting glass apparatus with a GL 60 connection.

Questions about tube GL 60 with restriction
What is this article?
tube GL 60 with restriction 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.
