Rotary evaporatorRotary evaporator is a commonly used equipment for evaporation, concentration, and solvent recovery in laboratories, widely used in fields such as chemistry, pharmaceuticals, biology, and food. It achieves efficient and mild solvent evaporation through the synergistic effect of rotating the sample bottle, reducing pressure, and heating.

　　Rotary evaporatorMain types:

Classified by heating method

Water bath type: suitable for solvents with lower boiling points (such as ethanol and acetone), with a temperature range of room temperature to 100 ℃.

Oil bath type: suitable for high boiling point solvents such as dimethyl sulfoxide and glycerol, with a temperature range of up to 180 ℃.

Classified by condenser tube design

Vertical condenser tube: simple structure, suitable for conventional evaporation.

Diagonal condenser tube: increases condensation area, improves recovery rate, suitable for high boiling point or volatile solvents.

Double condenser tube: a combination of main condenser and secondary condenser to further reduce solvent loss.

Classified by degree of automation

Manual type: requires manual adjustment of speed, temperature, and vacuum degree.

Automatic type: equipped with a digital control system that can preset programs to achieve automatic evaporation and solvent recovery.
