acetone water Results The Graphic 1: Illustration of influence of the rotation speed on the evaporation output. The graphic above shows that an increase of the rota-tion speed up to 400 rpm raised the evaporation out-put. Though, the evaporation rate decreased again at speeds above 400 rpm (acetone). The test series with

Rotary Evaporation - Chemistry LibreTexts

Fire up your rotovap with the vacuum open and slowly open the stopcock to allow it to pull solution from your Erlenmeyer into your bump trap. Do not let solvent accumulate in the evaporation flask faster than it is evaporating! That's a good way to fill up your evaporating flask all .

ORGANIC LABORATORY TECHNIQUES 8 8.1 ROTARY .

The rotovap works by increasing the rate of evaporation of the solvent by (1) reducing the pressure to lower the solvent boiling point, (2) rotating the sample to increase the effective surface area and (3) heating the solution. To use the rotovap, first make sure that the power is on (top right of the stand).
