Lab Equipment. Rotary Evaporator. Most reactions in organic chemistry are done in solution. After the reaction is finished however, a chemist must remove the solvent in order to isolate the product of the reaction. A rotary evaporator (“rotovap”) is an extremely useful tool for accomplishing this task.

The rotary evaporation process ensures that the sample receives an even, consistent heating from the warm liquid. This, in turn, creates a smoother distribution of the sample and a more uniform temperature without overheating. Thanks to digital temperature control, you can repeat your results with stunning accuracy, eliminating guesswork.
