Rotary evaporator's are used in laboratories to gently remove and recover solvents from a given mixture via evaporation. Rotary evaporation is done by heating a mixture while lowering the atmospheric pressure using a vacuum system. This lowers the boiling point of the solvent forcing a phase change from liquid to vapor. The vapor is then pulled into the path of the condenser by the …

We take advantage of this in our use of the rotary evaporator or rotovap. The diagram below is a generic rotary evaporator. The essential parts are shown. The rotary evaporator is used for removing a solvent well below its boiling point, leaving behind the less-volatile material that was dissolved in that solvent. This is especially essential for a less-volatile solvent which, if removed

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. An Inefficient Process. So far, we’ve discussed the impact of using a pump ...

A cooling bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.These low temperatures are used to collect liquids after distillation, to remove solvents using a rotary evaporator, or to perform a chemical reaction below room temperature (see Kinetic control).

Rotary evaporation is the process of reducing the volume of a solvent by distributing it as a thin film across the interior of a vessel at elevated temperature and reduced pressure. This promotes the rapid removal of excess solvent from less volatile samples. Most rotary evaporators have four major components: heat bath, rotor, condenser, and solvent trap. Additionally an aspirator or vacuum ...
