Review:: Basic construction of distillation apparatus Review 1. Evaporation part - where the mixture is made to evaporate by heating. 2. Separation/fractional part - This - This is where where the actual actual separation separation of solvent solvent and nonvolatile or less volatile components takes place. 3. Condensation/cooling part 4. Collection part - where the various condensates are collected. What is a rotary evaporator? A rotary evaporator is a specially designed instrument for the evaporationof solvent (singlestage or straight distillation) under vacuum.
Principle of operation of Rotary evaporators A rotary evaporator is is an instrument used used to evaporate solvents under vacuum with vacuum with the use of rotation and heat. The vacuum is used to lower the boiling temperature thus minimising damage to thermolabile substances. Rotation is Rotation is used to distribute the liquid as a thin film over the flask surface thus increasing the surface area for evaporation. Heat is Heat is applied through immersion of the flask in a water bath. Rotation leads to more efficient temperature transfer and reduces bumping and foaming compared with static distillation. As a result the the evaporation rate is regulated by: by : •
heating bath temperature,
•
size of flask,
•
vacuum pressure, and
•
speed of rotation.
The rotovap rotovap takes advantage of the the low boiling points of solvents solvents by creating creating an environment where the solvent will rapidly boil o leaving only your product.
onditions that are most conducive to boiling are! low air pressure and high temperature.
