Description
Reducing adapter with standard ground joint is a DURAN® glass laboratory component that connects dissimilar ground-joint sizes in distillation, extraction, and general glass apparatus assemblies. This adapter features a sleeve joint NS 29/32 and a core joint NS 60/46, enabling a stepwise reduction between larger and smaller standard ground joints while maintaining a vacuum- and vapour-tight seal. Manufactured from DURAN® borosilicate glass, it offers the chemical resistance and thermal stability expected of laboratory glassware used in organic synthesis, solvent handling, and multi-piece glass setups. The unit is supplied as a single piece from manufacturer Lenz and weighs 0,086 kg, making it a compact interconnect for modular glass systems. It belongs to glass components for distillation and extraction and to components with ground glass joints, supporting flexible configuration of condensers, flasks, and receivers. Clear joint designation (sleeve 29/32, core 60/46) simplifies selection and assembly on the bench, helping laboratories build reliable reducing transitions without improvised fittings.

Questions about Reducing adapter, w. stand. ground joint, DURAN®, sleeve 29/32, core 60/46
What is this article?
Reducing adapter, w. stand. ground joint, DURAN®, sleeve 29/32, 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.
