Rotary Evaporation to Remove Solvent | Protocol

Rotary evaporation is a technique commonly used in organic chemistry to remove a volatile solvent from a non-volatile compound of interest. Invented by Lyman C. Craig in 1950 the rotary evaporator, or rotovap, gently removes solvents from compounds using heat combined with reduced pressure to evaporate, dry, and purify samples for further downstream use.

During this process, each botanical is individually macerated to draw out its essential oils. Our two rotary evaporators 'Roberta' and 'Aretha' distil each botanical in glass, with the highest quality organic wheat spirit. The spirit vapour is then condensed at -8c and each botanical distillation is stored for the flavour to mellow.

How to accelerate the evaporation of water at temperature .

That is to lower the pressure. At a pressure of about 1% of atmospheric pressure (achievable with a standard laboratory water aspirated vacuum pump) water boils at about 10 celsius. Even water at 5 degrees celsius will evaporate quickly, especially in a system like a rotary evaporator that maximises the surface area of liquid.
