Description
Thread adapter GL 14 to cone NS 29/32 is a precision laboratory connector made from borosilicate glass 3.3 for reliable coupling of threaded and ground-joint apparatus. It converts a GL 14 screw thread to a standard NS 29/32 cone, enabling secure assembly of flasks, condensers, reactors and other glassware in chemical synthesis, distillation and analytical workflows. The borosilicate glass 3.3 construction provides excellent chemical resistance and thermal stability for everyday laboratory use. With a net weight of 0,020 kg, the compact single-piece adapter integrates easily into existing setups while maintaining a tight, leak-resistant seal. This adapter from manufacturer Rettberg supports flexible configuration of modular glass systems without the need for additional intermediate fittings. It is particularly suited to organic chemistry, preparative work and general laboratory applications where standardised joints and screw threads must be combined. The robust design ensures long service life under typical laboratory conditions and repeated assembly cycles.

Questions about Thread adapter GL 14 to cone size 29/32
What is this article?
Thread adapter GL 14 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.
