Description
Reducing adapter with standard ground joint is a precision laboratory glass component designed to connect apparatus sections of different joint sizes in distillation, extraction and general glassware assemblies. Manufactured from DURAN® borosilicate glass, it features a sleeve joint NS 29/32 and a core joint NS 19/26, enabling a secure, leak-resistant reduction between larger and smaller ground-glass connections. The adapter supports modular setup of condensers, flasks and receivers while maintaining chemical resistance and thermal stability typical of DURAN® laboratory glass. Supplied as a single piece weighing 0,035 kg, it integrates readily into existing jointed systems used in research, quality-control and preparative workflows. This reducing adapter from manufacturer Lenz is intended for routine laboratory use where reliable ground-joint geometry and dimensional accuracy are required. It belongs to the family of glass components for distillation and extraction and helps laboratories standardise connections without custom glassblowing. Clear joint sizing simplifies selection and replacement in multi-piece assemblies.

Questions about Reducing adapter, w. stand. ground joint, DURAN®, sleeve 29/32, core 19/26
What is this article?
Reducing adapter, w. stand. ground joint, DURAN®, sleeve 29/32, core 19/26 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.
