Description
Drying tube NS 19/26 is a bent laboratory drying tube intended for moisture control and gas drying applications in chemical and analytical glassware systems. It features a standard ground joint of NS 19/26 for secure connection to compatible flasks, condensers and apparatus trains used in organic synthesis, distillation and sample preparation. The bent geometry supports convenient orientation in confined setups while allowing packing with solid desiccants to reduce water vapour in gas streams or reaction atmospheres. This drying tube from manufacturer Witeg assists in protecting moisture-sensitive reagents and maintaining drier conditions during experimental procedures. Supplied as one piece with a net weight of 0,04 kg, it fits research laboratories, teaching environments and quality-control workflows. Compatibility with European NS joint standards ensures straightforward integration into multi-component assemblies. Typical uses encompass drying of air or inert gases, shielding hygroscopic materials and supporting anhydrous conditions in laboratory glass trains. The practical form promotes efficient handling and reliable performance in routine moisture-management tasks across scientific and technical settings.

Questions about Drying tube ST 19/26
What is this article?
Drying tube ST 19/26 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Labware.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
