Description
The adapter, socket NS 45/40 to cone NS 29/32 is a precision ground-joint transition piece manufactured from borosilicate glass 3.3. This reducing adapter connects laboratory glassware of differing standard joint sizes by providing an NS 45/40 socket that mates directly with an NS 29/32 cone. With a net weight of 0,078 kg it remains lightweight yet mechanically robust, offering the thermal-shock resistance and chemical durability characteristic of borosilicate glass 3.3. Produced by manufacturer Rettberg, the component is ground to tight tolerances that ensure a reliable, leak-tight seal in vacuum or pressure applications when used with appropriate grease or PTFE sleeves. Typical uses include organic-synthesis manifolds, distillation trains and multi-neck flask assemblies where a compact joint reduction is required. The material withstands most laboratory acids, bases and organic solvents, supporting a broad range of experimental conditions. Supplied as 1 pc, the adapter integrates seamlessly into existing DIN/ISO-standard glassware sets and enables flexible reconfiguration of reaction apparatus without custom fabrication.

Questions about Adapter, socket size 45/40 to cone size 29/32
What is this article?
Adapter, socket size 45/40 to cone size 29/32 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.
