Ethanol Extraction Using Rotary Evaporator - WKIE

A rotary evaporator, also known as a rotovap, is generally used in laboratories for efficient removal of solvents from samples using an evaporation process. Ethanol extraction uses alcohol as a solvent. It is a volatile flammable, colorless liquid that forms the intoxicating agent in alcohol drinks also called grain alcohol or ethyl alcohol.
