Dec 20, 2019 · Higher efficiency, together with better accuracy, is the primary advantage of using a rotary evaporator over distillation. A rotary evaporator is electronically controlled so that the rotation of the flask can be kept at a constant speed, and the mixture can form a film on the inner surface of the flask, creating a larger surface for heating.

A rotary evaporator works by the general assumption that at each given time, the boiling point of the solvent in question is much lower than the boiling point of the liquid surrounding it. As the boiling point of liquids slowly reduces when you decrease their pressure, it allows the solvent to be vaporized at lower temperatures than their standard boiling point at normal pressure.

Generally, the larger the evaporating flask, the greater the evaporation rate. This is because a larger flask allows for an increased velocity at the perimeter of the flask. With higher speed, the solvent inside the flask becomes more agitated and the active surface area of the solvent is enlarged. This all results in a higher evaporation output.

evaporation flask is carefully attached to the ground glass joint and secured with a clip (don't use grease). If the flask neck size doesn't match the joint on the rotary evaporator, then a reduction adaptor needs to be used. Start the flask rotating. Place your finger or thumb over the vent hole and use it to control the vacuum.
