Description
The fractionating column according to Vigreux is a precision laboratory distillation column of the Vigreux type. This PRECISO version is supplied without a glass jacket and carries a cone joint NS 29/32. It offers a packing height of 500 mm and contains 27 rings that generate multiple condensation–re-evaporation stages, thereby enhancing separation efficiency during fractional distillation. The column is delivered as 1 pc and has a net weight of 0,22 kg. Available from manufacturer Witeg, it is suited to organic synthesis, purification and solvent-recovery applications in research and quality-control laboratories. The characteristic internal indentations of the Vigreux design increase the effective surface area for vapour–liquid contact without requiring additional packing materials. With its 500 mm filling height the column provides greater separating power than shorter variants while remaining compatible with standard NS 29/32 ground-joint apparatus. It integrates readily into existing distillation setups where controlled fractionation of liquid mixtures is required.

Questions about Fractionating columns, acc.to Vigreux. P
What is this article?
Fractionating columns, acc.to Vigreux. P 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.
