Description
Vigreux column with cone NS 14,5/23 and socket NS 14,5/23, fitted with a vacuum jacket, is a precision distillation column for laboratory fractionation. A packing height of 300 mm and a diameter of 15 mm provide an extended separation path for fractional distillation of organic mixtures. Manufactured from borosilicate glass 3.3, the column combines chemical resistance with thermal stability under typical laboratory conditions. The vacuum jacket reduces heat loss along the column wall and helps maintain separation efficiency during distillation. Standard ground joints NS 14,5/23 enable straightforward connection to flasks and condensers in common glassware setups. This column from manufacturer Rettberg is intended for organic chemistry, natural-product isolation and solvent purification. With a net weight of 0,168 kg, the design suits small- to medium-scale preparative work. Vigreux indentations increase vapour–liquid contact surface without loose packing materials, offering a clean, reusable fractionation solution for research and teaching laboratories requiring longer effective column length.

Questions about Vigreux column, cone size 14,5/23, socket size 14,5/23, with vacuum jacket,
What is this article?
Vigreux column, cone size 14,5/23, socket size 14,5/23, with vacuum jacket, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Récipients de réaction & récipients à double enveloppe, inside Béchers & fioles, in Matériel de laboratoire.
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.
