Product Description
Better separation of close-boiling liquids does not always require packing material. This KIMAX Vigreux column uses glass indentations to increase surface contact, improving fractionation while staying easy to clean. It is a simple, reliable choice for teaching and research distillations alike.
This listing is for Kimble catalog number 21802-200: KIMAX Vigreux Distillation Column. The column is made from low-extractable, 33 expansion borosilicate glass meeting USP Type I and ASTM E438 Type I, Class A. Its inner tube has twelve sets of indentation rings about 14 mm apart, alternating horizontal and downward-slanted, and a drip tip at the lower end. It has a 200 mm length and 19/22 joints. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
