Description
Thread adapter GL 18 to cone NS 14,5/23 is a precision laboratory glassware connector fabricated from borosilicate glass 3.3. It provides a reliable transition from a GL 18 screw thread to a standard ground-joint cone NS 14,5/23, allowing flexible combination of threaded vessels, bottles and ground-joint apparatus in chemical and analytical laboratories. The borosilicate glass 3.3 material ensures high chemical resistance and thermal durability for everyday laboratory operations. With a net weight of only 0,008 kg, the compact single-piece design fits easily into modular glass assemblies while maintaining a secure seal. This adapter from manufacturer Rettberg supports efficient configuration of reaction setups, distillation trains and sample-handling systems. It is well suited to organic synthesis, preparative chemistry and general laboratory work where standardised joints and screw threads must be joined without compromising integrity. The robust construction delivers consistent performance under typical laboratory conditions and repeated use.

Questions about Thread adapter GL 18 to cone size 14,5/23
What is this article?
Thread adapter GL 18 to cone size 14,5/23 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.
