Beschrijving
Vigreux fractionating column PRECISO with ground joint NS 19/26 is laboratory glassware engineered for fractional distillation of liquid mixtures. It offers a filling height of 300 mm together with 16 rings and is supplied without a glass jacket, allowing direct mounting in standard distillation trains. The indented Vigreux design increases internal surface area to promote repeated vapour-liquid equilibration, improving separation of components that differ in boiling point. This column from manufacturer Witeg is intended for organic synthesis, solvent purification, essential-oil isolation and analytical sample work-up where controlled fractionation is required. The single-piece unit has a net weight of 0,088 kg and connects via the NS 19/26 joint to matching flasks, condensers and receivers. Its unjacketed construction simplifies visual monitoring of the distillation process and reduces thermal mass, supporting rapid equilibration. Suitable for research, teaching and quality-control laboratories, the column delivers reliable performance in routine and preparative-scale separations without the need for additional packing materials.
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 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.
