What is a rotary evaporator? - Kalstein

Aug 20, 2021 A rotary evaporator is a laboratory device used for the removal or recovery of solvents at low pressure. As its name indicates, it evaporates substances through the process of distillation, to later be condensed and later its components separated one by one. These equipment have existed in laboratories around the world since the 1960s, when the ...
