Beschreibung
Boiling capillary with cone NS 29/32 is a laboratory glassware accessory intended to promote even boiling and minimise bumping in larger-scale distillation and reaction vessels. Fabricated from borosilicate glass 3.3, the capillary combines high chemical resistance with good thermal stability for demanding laboratory conditions. The precision-ground cone joint guarantees a secure fit to corresponding NS 29/32 sockets. Offered as one piece with a net weight of 0,046 kg, it is well suited to preparative work and larger flasks. This boiling capillary originates from manufacturer Rettberg and bears the Rettberg® registered trademark. It finds application in organic synthesis, solvent recovery and general laboratory heating procedures where controlled vapour evolution is essential. The durable glass construction maintains joint integrity through repeated use and cleaning cycles. Compatible with standard European ground-joint apparatus, the item provides a straightforward solution for improving boiling behaviour without additional mechanical devices.
This article belongs on Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Air leak tube, cone size 29/32
What is this article?
Air leak tube, cone size 29/32 is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Laborbedarf.
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.
