Description
Reducing adapter with standard ground joint is a laboratory glassware component for connecting apparatus sections that use different joint sizes in distillation, extraction and related glass assemblies. This DURAN® piece combines a sleeve NS 45/40 with a core NS 60/46, allowing a controlled size transition between intermediate and larger standard ground joints while preserving a continuous, interchangeable joint interface. The adapter belongs to the family of ground-glass components used to build modular reaction trains, condensers, receivers and multi-stage distillation setups common in preparative organic chemistry and solvent work. Produced by manufacturer Lenz in DURAN® glass, it is intended for laboratories that rely on European standard ground joints for flexible reconfiguration of apparatus. Supplied as one piece with a weight of 0,104 kg, the reducing adapter supports repeated assembly and disassembly in teaching and research environments. Its defined sleeve and core dimensions help match existing glassware inventories without improvised couplings. Suitable for glass components, distillation bridges and extraction lines where reliable joint geometry is required for safe, reproducible laboratory practice.

Questions about Reducing adapter, w. stand. ground joint, DURAN®, sleeve 45/40, core 60/46
What is this article?
Reducing adapter, w. stand. ground joint, DURAN®, sleeve 45/40, core 60/46 is the article on this page. Luminix Health distributes Lenz 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.
