Description
Vapour duct 26 with standard ground joint NS 29/32 is a laboratory glassware component for rotary evaporator and distillation vapour paths. It provides a defined connection between the evaporating flask and the condenser assembly, supporting efficient vapour transfer during solvent removal and concentration work. The standard joint is NS 29/32; NS 24/29 is available on request for compatibility with alternative glassware sets. Supplied as a single piece, the duct is intended for routine use in research, quality-control and preparative laboratories. Net weight is approximately 0,080 kg, reflecting a compact glass construction suited to typical evaporator configurations. Offered by manufacturer Heidolph, this vapour duct complements modular evaporator systems where reliable ground-joint sealing and straightforward interchangeability matter. It is a practical spare or upgrade part for maintaining continuous evaporation workflows across aqueous and organic solvent applications without altering the core instrument setup.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Vapor tube - 26 NS 29/32
What is this article?
Vapor tube - 26 NS 29/32 is the article on this page. Luminix Health distributes Heidolph 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.
