Description
Vigreux column with cone NS 14,5/23 and socket NS 14,5/23 features an integral glass jacket and a filling height of 200 mm, fabricated from borosilicate glass 3.3 for laboratory distillation work. The indented Vigreux design increases surface area for efficient vapour-liquid contact, making the column suitable for fractional distillation of organic mixtures under atmospheric or reduced pressure. The pushed-on glass jacket provides thermal insulation and mechanical protection during operation. Offered as 1 pc with a net weight of 0,154 kg, this column from manufacturer Rettberg integrates standard ground-joint connections that mate directly with common laboratory glassware. The NS 14,5/23 joints ensure leak-tight assembly, while the 200 mm effective length balances separation efficiency with practical bench-top height. Ideal for synthetic chemistry, natural-product isolation and teaching laboratories, the all-glass construction resists most solvents and permits visual observation of the distillation process. Produced in Germany, the column supports reproducible fractionation without additional packing materials.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Vigreux column, cone size 14,5/23, socket size 14,5/23, with glass jacket,
What is this article?
Vigreux column, cone size 14,5/23, socket size 14,5/23, with glass 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.
