Description
Vigreux fractionating column PRECISO NS 29/32 with 600 mm packing height is a compact glass column intended for fractional distillation without an outer glass jacket. It is equipped with a ground cone NS 29/32 and contains 31 rings that increase the internal surface area available for vapour–liquid contact, thereby supporting efficient separation of close-boiling components. The open PRECISO design reduces thermal mass and simplifies cleaning while remaining fully compatible with standard NS 29/32 jointed glassware. A net weight of only 0,23 kg makes the column easy to handle and mount in laboratory distillation assemblies used for organic synthesis, solvent purification or analytical sample preparation. Supplied as one piece, this fractionating column from manufacturer Witeg delivers the classic Vigreux performance profile in a lightweight format suited to both teaching and research environments. Visual observation of reflux behaviour remains straightforward thanks to the unjacketed construction, allowing operators to adjust heating rates promptly during fractionation runs.

Questions about Fractionating columns, acc.to Vigreux. P
What is this article?
Fractionating columns, acc.to Vigreux. P 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.
