Description
Boiling capillary NS 29/32 is a laboratory glassware component intended for controlled boiling in distillation and reaction assemblies. It features an installation length of 200 mm together with a standard ground-joint core NS 29/32, enabling secure connection to matching flasks and apparatus. The capillary helps manage vapour flow and reduces bumping during heating, supporting smooth operation in organic synthesis, analytical work and routine laboratory procedures. Net weight is 0,039 kg, making the piece light and easy to handle while remaining compatible with common European joint systems. Supplied as a single piece, it integrates directly into existing glassware setups without additional adapters. This boiling capillary from manufacturer Witeg is suited to research, quality-control and teaching laboratories that rely on interchangeable NS joints. The straightforward design emphasises reliable fit, practical installation length and everyday durability, providing a dependable accessory for any well-equipped chemistry workspace where consistent boiling behaviour is required.

Questions about Air leak tubes, built-in length 200 mm,
What is this article?
Air leak tubes, built-in length 200 mm, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Têtes de distillation, adaptateurs & colonnes, inside Verrerie de distillation & d'extraction, in Matériel de laboratoire.
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.
