A rotary evaporator carries out distillation and drying batch-wise in a quick and efficient manner. The rotation of the flask increases the surface area of the mixture, thereby improving the heat transfer. Vacuum lowers the boiling point, enabling low-temperature distillation.

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate low boiling solvents such a n-hexane or ethyl acetate from compounds which are solid at room temperature and pressure.

Dec 18, 2018 The rotary evaporator functions on the general assumption that the boiling point of the solvent is much lower than that of the liquid surrounding it. It also assumes the compounds in the liquid are thermally sensitive; otherwise you could just boil the solvent out. A rotovap works by creating a vacuum in a rotating glass flask.

During the evaporation process, rotary evaporators reduce the pressure within the system to lower the solvent boiling point, rotating the sample to increase the effective surface area, and heat up the solution. It is most often and conveniently applied to separate ‘low boiling’ solvents such a n-hexane or ethyl acetate from compounds .

Mar 01, 2021 Reducing the pressure in the rotary evaporator has numerous benefits. Namely, the reduced pressure allows the evaporation process to take place far more quickly. In addition, the decrease in pressure will lower the boiling point of the solvent, which means the system will not need to implement high temperatures.

The rotary evaporator is the method of choice for solvent removal in the modern organic laboratory. The solvents or low boiling compounds are removed by a simple distillation. The rotovap is designed to be operated under a vacuum (to lower a compound's boiling point) while heating the sample at the same time.
