Description
Adapter, socket NS 14,5/23 to cone NS 19/26 is a compact ground-joint transition piece that bridges smaller and medium standard taper connections in laboratory glassware assemblies. Made from durable borosilicate glass 3.3, it provides outstanding resistance to chemicals and thermal shock, making it suitable for a wide range of experimental conditions. The female socket NS 14,5/23 accepts matching male joints, while the male cone NS 19/26 allows direct attachment to larger components. Delivered as one piece weighing 0,018 kg net, the adapter enables efficient scaling of apparatus for synthesis, fractionation or sample preparation. Its precise grinding ensures reliable sealing under vacuum or slight pressure when used with appropriate joint grease or sleeves. This component is particularly useful in teaching laboratories and research settings where modular glass systems are frequently reconfigured. Manufactured by Rettberg, it combines dimensional consistency with optical clarity for straightforward monitoring of processes. The lightweight design minimises stress on delicate glassware trains while maintaining mechanical stability throughout repeated use.

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