Apr 04, 2019 3. Solvent Loss. In a rotary evaporator process, you're often able to recover fairly high-purity solvent that can be reused. If your solvent doesn’t have time to condense into the collection flask, your solvent recovery rate is going to decrease. There’s no way to recover solvent that has made its way to the pump. 4.
