Description
Adapter, socket NS 24/29 to cone NS 14,5/23 is a ground-joint reducing piece for connecting laboratory glassware of different standard taper sizes. Made from borosilicate glass 3.3, it joins a female NS 24/29 socket to a male NS 14,5/23 cone, allowing flasks, condensers and other apparatus with mismatched joints to be assembled into one continuous train. The borosilicate 3.3 construction provides the chemical resistance and low thermal expansion expected in routine organic synthesis, distillation and general laboratory work. This single-piece adapter from manufacturer Rettberg has a net weight of 0,026 kg and is intended for modular glass setups where a reliable mechanical and vacuum-tight transition between NS 24/29 and NS 14,5/23 is required. Precision-ground joint surfaces support stable seating of compatible cones and sockets under atmospheric or reduced pressure. As a compact reducing adapter it simplifies apparatus design without intermediate couplings, helping laboratories maintain standardised joint geometry across multi-component assemblies while benefiting from the durability of borosilicate glass 3.3.

Questions about Adapter, socket size 24/29 to cone size 14,5/23
What is this article?
Adapter, socket size 24/29 to cone size 14,5/23 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.
