Description
Fractionating column according to Hempel NS 14/23 is a precision laboratory glassware item equipped with a glass jacket, NS 14/23 core joint and NS 14/23 sleeve joint, together with a filling height of 150 mm. Intended for fractional distillation, it enables efficient separation of liquid mixtures according to boiling-point differences in organic synthesis, purification and analytical workflows. The glass jacket supports thermal control and visual monitoring of the packing and vapour-liquid contact zone during operation. Supplied as a single piece with a net weight of 0,048 kg, the column integrates readily into standard laboratory assemblies that use NS 14/23 ground-glass connections. Manufactured by Witeg, this Hempel-type column offers a compact yet effective geometry suited to research, quality-control and teaching laboratories. Its robust borosilicate construction provides chemical resistance while the defined filling height of 150 mm ensures reproducible fractionation performance. The design is particularly useful when moderate separation efficiency and straightforward assembly are required for routine distillations.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about FRACTIONATING COLUMNS, ACC. TO HEMPEL,
What is this article?
FRACTIONATING COLUMNS, ACC. TO HEMPEL, 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.
