How We can Use Rotary Evaporator for Extraction? - Rotovap

The rotovap is a method that is commonly used to remove solvents in modern organic laboratories. The low-boiling compound or solvents are removed through a process of simple distillation. The rotary evaporator is made to work under a lowered pressure (vacuum), which is used to lower the boiling point of the compound while heating up the sample simultaneously.
