Product Description
Improve separation of close-boiling liquids at microscale without adding packing material. The indented column provides extra surface for vapor and liquid to interact, giving better fractionation than a simple distillation while remaining easy to clean. It is a natural upgrade for microscale kits that need more separating power than a simple head can provide.
This listing is for Kimble catalog number 746150-0000: KONTES Vigreux Distilling Column. This 75 mm column has indentations along its entire length and a 20-400 threaded top, with a 14/10 joint for connection to microscale flasks and heads. It is made from 33 expansion, low extractable borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A. Order it from LIGHT LABS and keep your lab stocked with genuine DWK Life Sciences products.
