Feb 15, 2021 Rotovaps work on the principal that the boiling point of a solvent is substantially lower than the compound it is dissolved in. The rotovap is operated under a vacuum to lower a compound’s boiling point whilst the sample is heated at the same time. When the pressure of a liquid decreases, the boiling point reduces and the solvent can be ...

Make sure the vent at the top of the cooling coils is closed. Turn the vacuum outlet on the vacuum system on. As the solvent evaporates, you may notice a lot of frothing and bubbling in the evaporating flask. If it starts bubbling out of the flask, you can open the vent a little (see picture above) to release some of the pressure.
