Description
Expansion adapter cone NS 24/29 to socket NS 29/32 is a precision ground-glass joint transition piece for linking laboratory glassware with differing standard joint sizes. It combines a male cone (Kern) NS 24/29 with a female socket (Hülse) NS 29/32, providing a secure, leak-resistant connection for distillation, reaction and vacuum assemblies conforming to DIN 12257. Delivered as one piece with a net weight of 0,04 kg, the adapter enlarges the joint diameter to accept larger apparatus while preserving the standardised taper geometry required for reliable sealing. From manufacturer Witeg, this component belongs to the established family of normschliff transition pieces used throughout organic synthesis, analytical chemistry and preparative laboratory practice. Robust glass construction permits repeated assembly and disassembly without loss of joint integrity or vacuum performance. Laboratories requiring dependable conversion between NS 24/29 and NS 29/32 systems can integrate the adapter directly into existing glassware trains, supporting modular apparatus layouts and flexible experimental configurations.

Questions about Expansions adapter ST 24/29 -> ST 29/32
What is this article?
Expansions adapter ST 24/29 -> ST 29/32 is the article on this page. Luminix Health distributes Witeg 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.
