Why Do We Use Rotary Evaporator? - WKIE LAB.com

Apr 29, 2020 · A rotary evaporator allows for a precise and gentle distillation conventional machines cannot provide. The main reason why rotary evaporators are better than traditional devices is that it removes the solvent under vacuum. Vacuum lowers the boiling point, therefore eliminating the need for high temperature for the distillation .

Vacuum distillation - Wikipedia

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.
