Description
Column heads NS 19/26 are precision laboratory glassware components intended for semi-micro distillation according to the Antlinger design. Equipped with a column ground joint NS 19/26, they enable controlled vapour management and efficient fractionation in compact apparatus. The single-piece unit has a net weight of 1,3 kg and a matching gross weight of 1,3 kg, reflecting solid borosilicate construction suited to repeated thermal cycling. These heads integrate readily with standard jointed glassware trains used in organic synthesis, solvent recovery and analytical sample preparation. Manufactured by Witeg, the Antlinger-style configuration minimises hold-up volume while supporting reliable separation performance on the semi-micro scale. Laboratories engaged in method development, teaching or routine purification benefit from the standardised NS 19/26 interface that ensures interchangeability with existing columns and condensers. The robust build supports safe handling under typical laboratory vacuum and atmospheric conditions, contributing to reproducible results in research and quality-control workflows where precise distillation control is required.
This article belongs on Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Column heads, acc. to Antlinger, cone t
What is this article?
Column heads, acc. to Antlinger, cone t is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Distillation heads, adapters & columns, inside Distillation & extraction glassware, in Matériel de laboratoire.
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.
