Description
Intermediate adapter KNS 24/29 to HNS 24/29 is a straight ground-glass transition piece for connecting laboratory apparatus that share identical NS 24/29 joints. Built to Form A2 geometry, it presents a core joint NS 24/29 on one end and a socket joint NS 24/29 on the other, fully compliant with DIN 12257. This configuration is commonly used to lengthen or bridge sections of distillation columns, reaction vessels and vacuum manifolds while preserving joint size and chemical resistance. The single-piece adapter has a net weight of 0,034 kg and integrates directly into standard ground-joint glassware. Manufactured by Witeg, it offers reliable interchangeability with other DIN-compliant components used in research, process development and teaching laboratories. The matched NS 24/29 dimensions ensure secure, leak-resistant seals when properly assembled, and the uncomplicated form facilitates cleaning and autoclave sterilisation where applicable. An essential spacer or extension element whenever same-size joint continuity is needed in modular glass apparatus.

Questions about Expansions adapter CST 24/29-> SST 24/29
What is this article?
Expansions adapter CST 24/29-> SST 24/29 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.
