Description
Drying tube NS 29/32 is a calcium chloride drying tube fitted with a standard ground joint NS 29/32 for secure, leak-free connection to laboratory glassware. It is routinely packed with desiccants to protect moisture-sensitive reactions, dry gas streams or closed systems against atmospheric humidity in organic synthesis and analytical work. The compact unit has a net weight of 0,062 kg and is supplied as a single piece ready for immediate incorporation into distillation trains, Schlenk lines or simple drying assemblies. Its NS 29/32 joint matches common European laboratory standards, allowing rapid assembly and disassembly without adapters. Produced by manufacturer Witeg, the tube combines practical geometry with durable glass construction suited to everyday laboratory demands. Applications include safeguarding hygroscopic reagents, maintaining anhydrous conditions during reactions and supporting teaching or routine quality-control workflows. The straightforward open design permits easy filling, emptying and cleaning between experiments, ensuring efficient reuse and reliable moisture control in research and educational environments.

Questions about Drying tube, bent, ST 29/32
What is this article?
Drying tube, bent, ST 29/32 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.
