Description
Threaded tube GL 80 constricted is a laboratory glassware element designed for attachment applications, supplied with a constricted section and ISO thread conforming to DIN 12216. Measuring 90 x 130 x 3,5 mm, the tube delivers a robust GL 80 connection point for larger vessels or apparatus modules. The constricted geometry facilitates secure mechanical joining while preserving flow characteristics in distillation, reaction or transfer setups. Available as one piece, this component from manufacturer Witeg supports the construction of modular glass systems that require standardised threaded interfaces. The ISO thread guarantees compatibility with common GL 80 caps, adapters and closures used in European laboratories. A wall thickness of 3,5 mm provides structural integrity for repeated handling and assembly. Researchers and process technicians select such tubes when expanding or customising glassware trains that demand reliable, leak-resistant ports. The defined dimensions ensure reproducible fit within existing laboratory infrastructure. This threaded tube constitutes a practical building block for analytical and preparative work where GL 80 connectivity is specified.

Questions about tube GL 80 with restriction
What is this article?
tube GL 80 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.
