Description
NS short adapter (reduction adapter) PTFE is a compact ground-joint reduction piece for connecting laboratory glassware of different standard taper sizes. It is made of PTFE and combines a core NS 19/26 with a socket NS 29/32, with the socket arranged on the core for a short overall length. This geometry supports neat, space-saving transitions in distillation, synthesis and general apparatus setups where a reliable NS reduction is required. PTFE provides broad chemical resistance and dimensional stability at the joint surfaces, making the adapter suitable for many organic and aqueous media used in routine laboratory work. The design belongs to the family of transition and standard ground-joint reduction components and is intended for modular glassware assemblies. Offered as a single piece with a net weight of 0,048 kg from manufacturer Witeg, the adapter integrates cleanly between matching NS 19/26 and NS 29/32 components. It is a practical choice whenever a short PTFE reduction between these two standard sizes is needed without introducing glass-to-glass contact at the adapter itself.

Questions about ST-short adapters (reduction adapter) PTFE
What is this article?
ST-short adapters (reduction adapter) PTFE is the article on this page. Luminix Health distributes Witeg 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.
