Description
Adapter, socket NS 24/29 to cone NS 19/26 is a ground-joint reducing piece that links laboratory glassware with different standard taper dimensions. Fabricated from borosilicate glass 3.3, the adapter presents a female NS 24/29 socket and a male NS 19/26 cone, enabling secure connection between components that would otherwise be incompatible. It is suited to distillation trains, reaction assemblies and everyday laboratory setups where standardised joints must be matched while preserving seal integrity. Supplied as one piece with a net weight of 0,029 kg, this transition adapter (Rettberg) combines the chemical durability and thermal-shock resistance characteristic of borosilicate 3.3. Precision-ground surfaces promote a stable fit with matching cones and sockets for work at ambient or reduced pressure. By bridging NS 24/29 and NS 19/26 in a single compact form, the reducing adapter supports modular apparatus construction and helps laboratories keep joint geometry consistent across multi-part glassware systems without additional couplings or improvised connectors.

Questions about Adapter, socket size 24/29 to cone size 19/26
What is this article?
Adapter, socket size 24/29 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.
