Description
Drying tube NS 24/29 is a laboratory drying tube, also known as a calcium chloride tube, developed for moisture absorption and gas drying within chemical glassware assemblies. It incorporates a standard ground joint of NS 24/29 that mates with compatible flasks, condensers and apparatus components employed in organic synthesis, distillation and analytical work. The tube provides internal volume suitable for packing solid desiccants such as calcium chloride, enabling removal of water vapour from gas streams or reaction environments. This drying tube from manufacturer Witeg helps safeguard moisture-sensitive compounds and supports drier operating conditions during laboratory procedures. Delivered as a single unit with a net weight of 0,048 kg, it serves research laboratories, educational facilities and industrial quality-control settings. Alignment with common European NS joint conventions permits simple connection into multi-piece glass systems. Applications include drying of air or inert gases, protection of hygroscopic materials and maintenance of anhydrous conditions in experimental setups. The functional design facilitates efficient moisture management and reproducible results in everyday scientific workflows.

Questions about Drying tube, bent, ST 24/29
What is this article?
Drying tube, bent, ST 24/29 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.
