Description
Adapter, socket NS 19/26 to cone NS 14,5/23 is a borosilicate glass 3.3 transition piece that connects dissimilar standard ground joints in laboratory apparatus. The socket side accepts NS 19/26 components while the cone side mates with NS 14,5/23 joints, enabling size reduction or expansion within a single glass train. Manufactured from chemically resistant borosilicate glass 3.3, the adapter withstands typical thermal and chemical loads encountered in organic synthesis, distillation and vacuum work. Supplied as a single piece with a net weight of 0,027 kg, it is a compact, reusable fitting for modular glassware setups. This adapter from manufacturer Rettberg (Rettberg ®) is produced in Germany and falls under laboratory glass adapters and reducing pieces. It supports clean, greaseable NS connections without intermediate tubing or plastic couplers, making it suitable for preparative benches, teaching labs and multi-neck flask assemblies that require reliable joint size conversion.

Questions about Adapter, socket size 19/26 to cone size 14,5/23
What is this article?
Adapter, socket size 19/26 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.
