Description
Adapter, socket NS 19/26 to cone NS 29/32 is a precision ground-joint transition piece designed for seamless connection of laboratory glassware with differing standard taper sizes. Fabricated from high-quality borosilicate glass 3.3, it offers excellent chemical resistance and thermal stability for demanding laboratory environments. The female socket NS 19/26 mates reliably with corresponding male joints, while the male cone NS 29/32 enables secure coupling to larger apparatus. Supplied as a single piece with a net weight of 0,025 kg, this adapter supports flexible assembly of distillation, reaction and extraction setups without the need for intermediate fittings. Its robust construction ensures vacuum-tight and leak-free performance when properly greased or used with PTFE sleeves. Ideal for organic synthesis, analytical chemistry and general laboratory work, the component integrates effortlessly into existing NS joint systems. Produced by manufacturer Rettberg, the adapter maintains dimensional accuracy according to common laboratory standards and facilitates quick reconfiguration of glass apparatus. The clear borosilicate material also allows easy visual inspection of contents and joints during operation.

Questions about Adapter, socket size 19/26 to cone size 29/32
What is this article?
Adapter, socket size 19/26 to cone size 29/32 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.
