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.
