Description
Reducing adapter with standard ground joint is a precision glassware component designed to connect laboratory apparatus that use different joint sizes in distillation, extraction and general assembly work. This DURAN® reducing adapter combines a sleeve joint NS 45/40 with a core joint NS 29/32, allowing a secure, leak-resistant transition between larger and smaller ground-glass connections without improvised fittings. Supplied as a single piece and weighing 0,055 kg, the adapter integrates cleanly into modular glass setups where dimensional accuracy and chemical resistance of borosilicate glassware are essential. The component is intended for use with matching standard ground joints in laboratory glass systems and supports reproducible configuration of condensers, receivers, flasks and intermediate pieces. Manufactured by Lenz, it belongs to the family of ground-glass joint components used throughout analytical, preparative and teaching laboratories. Clear sleeve and core designations simplify selection when building or modifying apparatus trains, helping maintain alignment and joint integrity under typical laboratory vacuum or atmospheric conditions. Ideal for glassware kits that require a reliable 45/40 to 29/32 reduction step.

Questions about Reducing adapter, w. stand. ground joint, DURAN®, sleeve 45/40, core 29/32
What is this article?
Reducing adapter, w. stand. ground joint, DURAN®, sleeve 45/40, core 29/32 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.
