A rotary evaporator is a laboratory instrument used to gently, efficiently remove solvents from samples by evaporation under reduced pressure. This process is especially important in chemistry and biochemistry for preparing samples before analysis or further synthesis.

The principle of operation of a rotary evaporator is based on reducing the pressure above a solution, which allows the solvent to evaporate at a much lower temperature than its normal boiling point. The sample is placed in a spinning flask that is partially submerged in a water or oil bath. Rotating the flask increases the surface area of ​​the solution, speeding up the evaporation process. The solvent vapor is condensed in a cooling trap and collected in a separate vessel, while the concentrated sample remains in the flask.
The main advantages of a rotary evaporator include high efficiency, the ability to work with minimal volumes of solvent, time savings due to rapid evaporation, and safety of use due to operation under reduced pressure and in a closed system, which reduces the risk of exposure of the user to harmful fumes.

Our laboratory has a rotary evaporator RE100-Pro
The device is equipped with a digital display with control of rotation speed and heating temperature, which allows optimal control of all distillation processes. Automatic motor lift releases the evaporation flask to a safe position in the event of a power failure, and the 5L heating bath with a wide temperature range from room temperature to 180°C allows the equipment to be used for the distillation of high-boiling liquids. The remote function provides PC control and data transfer.
