Feb 25, 2021 · It involves placing a sample within a round-bottomed flask, which is then placed in the rotovap’s heated water bath and rotated. A vacuum pump reduces the pressure above the solvent. This draws the solvent away from the sample (distributed as a thin film across the flask’s interior, while the compound remains.
