Mar 01 2020 Evaporation of solvent 70 methanol in oven at 40 C allowed to conserve higher quantity of phenolic compounds than air evaporation and rotary evaporator methodsThis may be due to the process of evaporation in oven which was carried out in dark compared to two other methods done in light.
May 26 2006 I agree with Peter that evaporation under nitrogen is easier to handle than rotary evaporationTo my experience evaporating 3mL of methanol under a gentle stream of nitrogen at 4050 degree celcius takes about 45 minutesRotary evaporation is always faster than nitrogen purgeThus evaporating 1mL of methanol should be less than 15 minutes.

What are Rotary Evaporators A rotary evaporator also called as rotavap or rotovap is a device used in labs for the efficient and gentle removal of solvents from samples by evaporationThe picture on the right shows what a typical rotary evaporator includes.
The performance of the POWERVAP is approxFactor 5 compared with a manual rotary evaporator system which has the same size of rotating flask.
The purpose of using the rotary evaporatorWe use the rotary evaporator rotovap for two main purposes 1To concentrate nonvolatile components in a mixture for example concentrating the purest and freshest flavors from a blood orange by removing the water 2To extract the volatile aroma and flavor molecules from mixtures gently and at.
Used to heat samples and control the temperature• Usually 4060 degrees Celsius is sufficientThe water bath temperature should not exceed the boiling point of the solvent • The condenser could be overloaded since the evaporation rate will exceed the condensation capacity.
