Description
Fractionating column according to Hempel NS 29/32 is a laboratory glassware item designed for high-efficiency fractional distillation and the separation of liquid mixtures according to differences in boiling point. Featuring a glass jacket, core joint NS 29/32 and socket joint NS 29/32, the column provides an extended filling height of 500 mm that increases the available surface for vapour–liquid equilibrium and thereby improves separation resolution. The jacketed construction assists in maintaining thermal uniformity along the packing zone, supporting stable operation during organic synthesis, solvent purification, essential-oil isolation and other preparative tasks. Delivered as one piece with a net weight of 0,504 kg, the column fits standard NS 29/32 ground-joint assemblies used in research, development and quality-control laboratories. Produced by manufacturer Witeg, this Hempel-type fractionating column offers reliable dimensional consistency and mechanical durability for repeated laboratory use. The longer 500 mm packing section accommodates a wide choice of packings, allowing users to tailor hold-up and theoretical-plate performance to the specific mixture under study. Clear geometry and well-defined joints simplify connection to flasks, condensers and receivers, while the glass mantle contributes to process control and operator safety during extended distillation runs in both academic and industrial settings.

Questions about Fractionating column Hempel ST 29/32 length 500 mm
What is this article?
Fractionating column Hempel ST 29/32 length 500 mm 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.
