Description
Fractionating columns according to Vigreux PRECISO without glass jacket provide reliable performance for fractional distillation in the laboratory. This model is equipped with a cone joint NS 29/32, a packing height of 100 mm and four rings that create an extended surface for vapour–liquid exchange. The classic Vigreux indentation pattern promotes efficient separation of liquid mixtures according to boiling-point differences, making the column suitable for organic synthesis, purification steps and preparative work. Supplied as a single piece with a net weight of 0,034 kg, the jacket-free design allows flexible external temperature control while remaining fully compatible with standard NS 29/32 glassware assemblies. The PRECISO series item from manufacturer Witeg is intended for routine and research distillation set-ups where precise joint geometry and consistent fractionation behaviour are required. Its compact dimensions support space-efficient apparatus configurations on the bench or in fume hoods, helping laboratories achieve reproducible results in multi-component separations.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Fractionating columns acc. to Vigreux
What is this article?
Fractionating columns acc. to Vigreux is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Labware.
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.
