Aug 20, 2021 A rotary evaporator is a laboratory device used for the removal or recovery of solvents at low pressure. As its name indicates, it evaporates substances through the process of distillation, to later be condensed and later its components separated one by one. These equipment have existed in laboratories around the world since the 1960s, when the ...

Evaporator. The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it. This causes the ...

How does the rotary evaporator work? The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).
