What Are Rotovaps and How Can They be Used?

2022-4-2 · What is a rotovap? A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. A rotovap acts like a filter to separate the unwanted components in the extract as a final step to crude oil. The rotovap is a simple concept with a lot of moving parts.
