Rotary evaporation is accomplished using a rotary evaporator, also known as a rotovap or rotavap. It is a commonly used technique for separating a compound of interest from a low-boiling solvent, such as an organic, inorganic, or polymeric substance. Separation is accomplished by heating a mixture of solvent and compounds inside an evaporation ...

The motor in the rotovap turns the flask rapidly, providing a greater surface from which evaporation can occur and speeding up the process. Cooling coils in the rotovap condense the vapors and drop them into a collection flask so that they can be recycled or properly disposed. The roto-vap is connected to a vacuum source, and again, this speeds ...
