Description
Fractionating column according to Hempel with NS 14/23 ground joint is a precision glassware component designed for laboratory distillation and separation work. The column follows the classic Hempel design in the PRECISO series, is supplied without a glass jacket and features a core joint of NS 14/23 together with a packing height of 300 mm. This configuration allows efficient vapour–liquid contact when the column is filled with suitable packing material, supporting fractional distillation of liquid mixtures under atmospheric or reduced pressure. The absence of an outer jacket keeps the assembly compact and easy to integrate into standard distillation setups. Manufactured by Witeg, the column is intended for use in organic synthesis, solvent purification and teaching laboratories where reliable fractionation performance is required. Supplied as a single piece, it connects directly to flasks and condensers equipped with matching NS 14/23 joints, enabling quick assembly of complete distillation trains for research or quality-control applications.

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