Description
Thread adapter GL 14 to cone NS 14,5/23 is a precision laboratory transition piece manufactured from borosilicate glass 3.3. It provides a reliable connection between GL 14 screw-thread fittings and the standard ground-joint cone NS 14,5/23, enabling flexible assembly of reaction vessels, distillation apparatus and other glassware systems. The single-piece adapter carries the registered trademark Rettberg ® and is supplied by manufacturer Rettberg from Germany. With a net weight of only 0,008 kg it remains lightweight yet mechanically robust for everyday laboratory use. Borosilicate glass 3.3 offers the chemical resistance and thermal stability required for a broad range of synthetic, analytical and preparative applications. This adapter simplifies the integration of threaded bottles or vessels into classical ground-joint setups, reducing the need for multiple intermediate components. Its compact design supports clean, leak-resistant joints in both research and teaching laboratories. The product type is classified as an adapter and is intended for permanent or semi-permanent glassware configurations where dimensional accuracy and material purity are essential.

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