Fractionating column according to Vigreux PRECISO without glass jacket is a compact laboratory distillation column intended for fractional separation of liquid mixtures. Equipped with a core joint NS 24/29, a filling height of 600 mm and 31 rings, the open Vigreux design maximises internal surface area for repeated vapour–liquid equilibration. Absence of an outer jacket keeps the column lightweight at a net weight of 0,224 kg while still providing excellent fractionation efficiency for components of similar boiling points. Packaged as 1 pc, it integrates directly into standard ground-joint distillation assemblies. This PRECISO-series column from manufacturer Witeg is particularly useful in organic chemistry, analytical sample preparation and educational settings where rapid set-up and clear visibility of the distillation process are advantageous. The robust glass construction ensures chemical resistance and durability under routine laboratory heating and vacuum conditions, supporting reproducible purification workflows.

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 Reaction vessels & jacketed vessels, inside Beakers & flasks, in Labmateriaal.
A reaction vessel is the flask a synthesis actually runs in, sometimes jacketed so a fluid can heat or cool the wall. The joints, the working volume and the jacket connections are the specification. It is not a storage bottle.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
