Beschrijving
Distilling column according to Hempel with cone NS 14,5/23 and socket NS 14,5/23 is a compact packed column for simple fractionation. It offers a packing height of 200 mm and is equipped with a glass jacket together with an integrated packing support. Made from borosilicate glass 3.3, the column delivers the chemical durability and thermal stability required for routine laboratory distillations. The NS 14,5/23 ground joints ensure leak-tight coupling to compatible small-scale glassware. This jacketed Hempel design from manufacturer Rettberg is intended for straightforward fractionation tasks where thermal insulation of the packing section is advantageous. Net weight is 0,158 kg. The combination of borosilicate construction, defined packing height and glass jacket supports controlled vapour–liquid contact in educational and research settings while remaining easy to clean and inspect.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Distilling column type Hempel, cone size 14,5/23, socket size 14,5/23,
What is this article?
Distilling column type Hempel, cone size 14,5/23, socket size 14,5/23, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Destillatiekoppen, adapters & kolommen, inside Destillatie- & extractieglaswerk, in Labmateriaal.
A still head, an adapter or a column is the glass between the boiling flask and the condenser. A Vigreux or packed column gives the vapour a surface so a closer-boiling mixture can separate. The joint sizes at both ends have to match the flask and the condenser.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
