30L Vacuum Distillation/Rotovap Kori Instrument

A rotary Evaporator is a device used in Extraction laboratories for efficient and gentle distillation of solvents from samples by evaporation. The rotating flask continuously covers a large surface area with a thin film which is ideal for rapid heat transfer. Fortuitously, the thin film also ensures uniform heat distribution without local heating.

Fractional Distillation for Solvent Recovery - extraktLAB

A thin film forms on the sides of the spinning glass that enables quick evaporation of the solvent. Once evaporated, the vaporized components are collected on a chilled condenser and conveyed away to a receiving flask. To further ease the removal of residual solvents, a rotovap creates a thin film of oil on the inside of the rotating flask.
