Description
Adapter, socket NS 29/32 to cone NS 71/51 is a precision ground-joint transition piece intended for laboratory glassware systems that require a change between standard taper sizes. Fabricated from borosilicate glass 3.3, the adapter presents a female socket NS 29/32 leading to a male cone NS 71/51, enabling reliable coupling of larger apparatus components. Borosilicate glass 3.3 is the established material for such fittings because of its resistance profile under typical laboratory conditions. Supplied as one piece with a net weight of 0,106 kg and produced in Germany, it bears the Rettberg ® registered trademark. Laboratory users can incorporate this transition piece from manufacturer Rettberg into distillation trains, reaction vessels or vacuum lines whenever an NS 29/32 to NS 71/51 reduction is needed. The design ensures stable, interchangeable connections that maintain system integrity across repeated assembly and disassembly cycles common in research and analytical work.

Questions about Adapter, socket size 29/32 to cone size 71/51
What is this article?
Adapter, socket size 29/32 to cone size 71/51 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.
