Vacuum Evaporation - an overview ScienceDirect Topics

A simple evaporator system has a single evaporation chamber or “effect”. An increase in the number of “effects” can boost the economy of the evaporator. A multiple “effect” system uses the vapor from the first “effect” as the steam source for each subsequent “effect”.

Common Issues With Rotary Evaporator Systems - USA Lab

During the process of rotary evaporation, a vacuum is used to reduce the pressure in the rotary evaporator to decrease the boiling point of the solvent so that it will evaporate more quickly. In some cases, however, the system may not be able to hold a vacuum which will prevent the process from being carried out efficiently.

Oct 05, 2020 By adding heat and reducing the pressure inside the rotary evaporator through the vacuum pump, the substance with lower boiling point evaporates. The vapour travels to the cooled condenser and condenses there. It thus changes from the gaseous state to the liquid state again and is collected in the receiving flask below the condenser.

What is the purpose of using the rotary evaporator?

When the vacuum is created, the gas molecules will begin to condense on the cold surface. The required conditions are such that evaporations continue simultaneously from the whole surface, including from inside the liquid. The result is bubbling, which is another reason why a rotary motor is used in evaporation.
