A rotary evaporator (rotovap or rotatvap) refers to a kind of equipment for solvent evaporation under reduced pressure, which is composed of a vacuum system, a heated water or oil bath, a condenser and a motor that rotates the evaporation flask. ... Turn on the speed control switch and the green light is on, adjust the speed knob on the left ...

A rotovap attains speeds of 10-280 rpm, but anywhere between 250-280 rpm is considered an optimal speed. Some devices offer speeds above 300 rpm, which will generate higher rates of efficiency, but greater chances of unwanted wear-and-tear.

Oct 24, 2015 This will help the speed be as smooth as possible, which will create a slight bubbling effect. This is the maximum proportional effect we want when recovering alcohol. When you being to run your rotovap we suggest starting at 150mbar, then step to 100mbar. Within this time, the flask temps will increase and begin sending vapor up.
