Why Do We Use Rotary Evaporator? - WKIE

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 process to occur.

Jan 12, 2021 The refrigerator evaporator is one part of the refrigeration cycle that makes the inside of your refrigerator cold. After the refrigerant gas has gone through the condenser coils located at the back of the refrigerator, it starts to cool down and turn into a liquid. It’s at this liquid stage that the refrigerant reaches the expansion valve.
