Description
Thread adapter GL 14 to cone NS 19/26 is a precision laboratory transition component fabricated from borosilicate glass 3.3. It creates a secure interface between GL 14 threaded connections and the larger standard ground-joint cone NS 19/26, allowing straightforward coupling of screw-thread vessels to classical glassware assemblies. Supplied as a single piece, the adapter bears the registered trademark Rettberg ® and comes from manufacturer Rettberg in Germany. Net weight is 0,012 kg, offering a light yet durable solution for routine laboratory setups. Borosilicate glass 3.3 ensures excellent resistance to chemical attack and thermal shock, making the adapter suitable for synthesis, distillation, extraction and general preparative work. The design reduces the number of intermediate fittings required when integrating modern threaded bottles into traditional ground-joint systems. Accurate dimensions promote leak-resistant joints essential for safe and reproducible experimental work. Classified as an adapter, this component supports both research and educational laboratories that demand reliable material quality and precise dimensional compatibility across mixed glassware configurations.

Questions about Thread adapter GL 14 to cone size 19/26
What is this article?
Thread adapter GL 14 to cone size 19/26 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.
