Rotary evaporator | Welch Vacuum by Gardner Denver

Rotary evaporators are typically used to remove solvents following chemical reactions. Combined with gentle heat from the evaporator bath, controlled vacuum is used to bring solvents to boiling or near-boiling. Efficient solvent distillation requires vacuum balanced to achieve sufficient pressure reduction and molecular flow without losing sample or overrunning the condensing capabilities of .

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.
