A rotary evaporator, sometimes referred to as a rotovap, is used to efficiently and gently remove solvents by evaporation. You can use a rotary evaporator to remove low boiling solvents from a compound, such as n-hexane or ethyl acetate. Rotary evaporators are the method of choice for distillation in lab grade applications.

Although this operation could, in principle, be performed by simple distillation, the fastest and most convenient method is the use of a rotary evaporator (rotovap) for distillation under reduced pressure. Basically, it consists of an electric motor, which causes the rotation of a tube attached to a ground glass-oint guide tube.

Apr 21, 2018 A rotary evaporator or other vacuum distillation instruments is used at this time to remove ethanol. If you choose cryogenic ethanol instead of warm ethanol, don’t forget to winterize the concentrate.Ethanol is classic, efficient and safe, but of course it is not the only option for cannabis extraction.

Jan 20, 2015 Achieve higher distillation efficiency when using a rotary evaporator – Impact of temperature differences There is a direct relationship between the heating bath temperature and the evaporation rate. The more energy applied to the evaporation side, and at the same time removed from the condensation side, the more efficient is the distillation.

Jul 21, 2017 Understanding Rotovap Distillation. Before learning about rotovap setup and operation, you must have a clear picture of the physical change happening inside of the rotary evaporator. Consider how a mixture containing extract and ethanol must first be separated before rotovap distillation can occur.

Like vacuum distillation, steam distillation is a method for distilling compounds which are heat-sensitive. This process involves using bubbling steam through a heated mixture of the raw material. ... This technique is referred to as vacuum distillation and it is commonly found in the laboratory in the form of the rotary evaporator.

The rotary evaporator can seal and reduce pressure to 400-600 MMHG. The solvent in the evaporation flask is heated with a heating bath. The heating temperature can be close to the boiling point of the solvent, at the same time, rotating the evaporation flask, the rotating speed could keep at 50-160rpm/min, make the solvent being thin film, increase evaporation area.
