Description
NS short adapter (reduction adapter) PTFE is a compact ground-joint reduction fitting for connecting different standard taper sizes in laboratory glassware assemblies. Made of PTFE, the adapter combines a core of NS 14/23 with a sleeve of NS 19/26, with the sleeve arranged on the core for straightforward reduction between these joint sizes. Supplied as 1 pc with a net weight of 0,017 kg, it suits chemical and analytical setups where an inert polymer contact surface is preferred. This short reduction adapter from manufacturer Witeg helps laboratories join apparatus of differing NS dimensions without glass-to-glass mismatch. PTFE construction supports chemical resistance in many common laboratory environments and simplifies handling compared with fragile glass reducers. The compact short-adapter format keeps overall assembly height low, which is useful in crowded fume-hood or bench configurations. It is well suited to organic synthesis, sample preparation and general laboratory glassware systems that rely on standard NS joints for modular apparatus build-up.

Questions about ST-SHORT ADAPTERS (REDUCTION ADAPTERS)
What is this article?
ST-SHORT ADAPTERS (REDUCTION ADAPTERS) 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.
