Description
Connecting pieces for tubing in straight form with stopcock and socket NS 29/32 provide a robust glass link between flexible hoses and standard ground-joint apparatus. Made from heat-resistant, durable borosilicate glass, the adapter incorporates a straight hose connector and a PTFE stopcock for precise on/off control. The excellently ground joint creates a leak-tight seal that prevents escape of air or liquids under normal laboratory conditions. Compatible with tubing diameters from 6 to 10 mm, the hose end suits common laboratory flexible tubing. Offered as a single piece from manufacturer ISOLAB Laborgeräte, this straight connector is well suited to larger NS 29/32 assemblies used in distillation, vacuum work and general fluid handling. The combination of borosilicate glass and PTFE ensures chemical resistance and smooth stopcock action, while the straight geometry maintains an unobstructed flow path. A practical choice whenever a reliable, heat-stable tubing-to-joint transition with shut-off capability is needed.
This article is part of Stopcocks & valves, in Tubing, hoses & fittings.

Questions about adapters - with nozzle - straight - with stopcock - socket : NS 29/32
What is this article?
adapters - with nozzle - straight - with stopcock - socket : NS 29/32 is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Matériel de laboratoire.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
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.
