Rotary evaporators are distillation units that incorporate an efficient condenser with a rotary flask system. As the flask containing the solvent is rotated it continually transfers a thin layer of liquid over the entire inner surface.
Controlling the vacuum also reduces the build-up of oscillation and improves solvent recovery and reproducibility. Manual vacuum control uses a stopcock or a manual valve and the vacuum level is adjusted by sight. With this method, the whole process must be closely monitored as the level of vacuum required can change during evaporation.

Laboratory rotary evaporator is a kind of laboratory equipment that facilitates the extraction of solvents and handing many experiments at the laboratory level.They are miniature size yet well able to handle a couple of chemical reactions and other issues that ordinarily transpire in the laboratory.
Rotary evaporators are commonly used in chemistry related environments for the efficient and gentle removal of solvents from samples by evaporation under vacuum. The evaporator consists of a heating bath with a rotating flask, in which the liquid is distributed as a thin film over the hot flask wall surfaces so it can evaporate easily.

Vacuum distillation is distillation performed under reduced pressure, which allows the purification of compounds not readily distilled at ambient pressures or simply to save time or energy. This technique separates compounds based on differences in boiling points. This technique is used when the boiling point of the desired compound is difficult to achieve or will cause the compound to decompose.
