Buchi Vacuum Rotary Evaporator

The Buchi Rotavapor Model R-200 in our laboratory is a vacuum rotary evaporator used for quick single stage distillation that treat the product gently. The process is based on the evaporation and condensation of solvents in a rotating evaporating flask. Distillation may be done either under a vacuum or at atmospheric pressure. The vacuum distillation ensures gentler treatment of the product and increase productive output. Some of the important applications of vacuum rotary evaporator in a research laboratory are evaporation of solvents and suspensions, recycling and concentration of solvents, drying of powders and granulates, re-crystallization, reaction under reflux and synthesis and cleaning of refined chemicals.
