Description
Hempel fractionating column 200 mm is a glass separation column used to improve the efficiency of fractional distillation by providing an extended vapour–liquid contact path. The Hempel design is a classic open-tube column that can be packed with suitable packing material when higher separating power is required. With a working length of 200 mm, the column offers a practical balance between resolution and hold-up for laboratory-scale distillations. Connection geometry comprises one FA 12 joint and one GL 25/12 threaded neck, allowing straightforward integration into standard distillation assemblies with round-bottom flasks and condensers. Produced by manufacturer Witeg, the column is intended for organic synthesis, solvent purification and boiling-point separation tasks. Net weight is 0,07 kg, keeping the overall glassware train light and stable on common laboratory stands. The 200 mm Hempel column is a versatile intermediate component between simple distillation heads and more elaborate packed or Vigreux columns when moderate fractionation is needed.

Questions about Fractionating columns, Hempel, 200 mm,
What is this article?
Fractionating columns, Hempel, 200 mm, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Têtes de distillation, adaptateurs & colonnes, inside Verrerie de distillation & d'extraction, 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.
