How to use a Rotary Evaporator

How to use a Rotary Evaporator

Apr 01, 2010 The flask with the solution is placed on the rotary evaporator. The use of a bump trap prevents the solution from accidentally splashing into the condenser (and being contaminated). It is highly advisable to start with a clean bump bulb in case something bumps over after all! This would allow the experimenter to recover the solution or solid. 3.

Feb 15, 2021 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 vaporized at a lower temperature than their standard boiling point. A cold finger is used to condense the vapors to a liquid which is ...

It can also be seen from the graph that for toluene the vapor pressure equals atmospheric pressure at a temperature of 111 C. The BP of toluene is therefore 111 C. Note that at any given temperature the vapor pressure of cyclohexane is greater than the vapor pressure of toluene. Consider next the behavior of a mixture of two liquid compounds.

May 08, 2020 In general, your bath temperature should be 20C higher than the boiling point of the substance you want to evaporate. And your coolant should be 20C or more lower than the vapor temperature. For example, if the boiling point of your substance is 40C, a bath temperature of 60C and coolant temperature of 20C should provide an optimal setup.
