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 ...
