What are the advantages and disadvantages of a rotary evaporator?

The rotary evaporator is now widely used in small and medium-sized experiments, and is used in laboratories for distillation, concentration, crystallization, purification, separation and other experimentsbasic equipmentInstruments. The experimental sample is subjected to vacuum distillation in a spherical flask, and a thin film is formed under the action of centrifugal force by constant rotation, thereby increasing the evaporation area and improving the evaporation efficiency.

Advantages of rotary evaporator:

1) Fast drying speed.

2) A single sample with a large volume can be processed at once.

3) The price is cheap.

Disadvantages of rotary evaporator:

1) Heating methods cannot guarantee biological activity.

2) Unable to handle highly volatile and highly corrosive samples.

3) The mixed solvent cannot be recovered separately.

4) Processing samples with a single specification.

5) Unable to process trace samples.
