The solvent to be evaporated is present in the evaporator flask (2). Depending on the
thermodynamic properties of the solvent, the solvent is evaporated by a suitably selected
combination of the heating bath temperature (3) and the vacuum. The settings are made
on the control panel (5) of the base unit (4). The drive unit (1) provides a rotation, which
reduces the risk of boiling evaporation and accelerates the evaporation process by in-
creasing the surface area of the solvent. The solvent vapor reaches the condenser (7)
via the vapor tube, is condensed and then flows into the receiving flask (6).
