A rotavap, also known as a rotatory evaporator is an apparatus used in chemical laboratories for the removal of solvents from samples through evaporation.
It can also be used in preparations of distillates and extracts. The rotatory evaporator is designed to work under a vacuum; to lower the boiling point of molecular compounds and heating the sample at the same time. The rotavap works by
- Increasing the evaporation rate of solvents.
- Rotating the samples to increase the surface area of action.
- Heating the organic solution.
The Main Components of A Cheap Rotavap Are:
– A motor that rotates vials containing the sample
– A condenser; usually consists of a coil which passes the coolant or has a system where the coolant mixtures are placed.
-Vacuum system that reduces pressure in the evaporator system.
– Vapor duct for sample rotation.
– Water bath to heat the samples.
– A collecting jar at the bottom of the condenser. It holds the distilling solvent.
– A mechanized system that lifts the evaporation flask from the heating bath.
The vacuum system used in rotavaps is usually a water aspirator with a trap that is immersed in a cold bath.
In modern rotatory evaporators, there have been additional features such as vapor temperature sensor, digitalized temperature display speed rotation.
