Description
Thread adapter GL 32 to cone NS 29/32 is a robust laboratory connecting element designed to link larger GL screw-thread fittings with standard NS ground-joint systems. Constructed entirely from borosilicate glass 3.3, it provides outstanding resistance to chemical attack, thermal stress and mechanical wear encountered in demanding experimental environments. The GL 32 thread accommodates correspondingly sized bottles, caps or tubing adapters, while the NS 29/32 cone ensures a precise fit into conical ground-joint apparatus commonly used for distillation, reaction and extraction work. At a net weight of 0,034 kg the adapter offers a stable, well-balanced form factor suitable for repeated use. Manufactured by Rettberg in Germany, this transition piece supports leak-tight modular assemblies under vacuum or atmospheric conditions. The inherent purity and low thermal expansion of borosilicate glass 3.3 help maintain sample integrity and apparatus longevity. Supplied as a single unit, the adapter streamlines glassware configuration in research, quality-control and process laboratories that depend on reliable, standardised connections between GL-threaded components and NS 29/32 joints.

Questions about Thread adapter GL 32 to cone size 29/32
What is this article?
Thread adapter GL 32 to cone size 29/32 is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Hose connectors, adapters & fittings, inside Tubing, hoses & fittings, in Matériel de laboratoire.
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.
