rotavap-controller1

The digital controller on a rotary evaporator enables precise control of temperature, rotation speed, and vacuum levels. Real-time data display and programmable functions enhance accuracy and safety. With an intuitive interface, it streamlines operations, making solvent distillation more efficient.

Connecting a rotary evaporator to a recirculating chiller ensures efficient solvent condensation during evaporation. The chiller maintains a stable low temperature in the condenser, improving recovery rates, reducing vapor loss, and protecting the vacuum pump from moisture or chemical damage.

Enhanced Evaporation Process

This rotary evaporator speeds up solvent removal through four integrated functions:

  • Reduced Pressure: Lowers the solvent’s boiling point, allowing faster evaporation at lower temperatures.
  • Sample Rotation: Increases surface area exposure, accelerating the evaporation rate.
  • Controlled Heating: Maintains precise temperatures to support optimal solvent separation.
  • Efficient Condensation: Captures vapor through a glass condenser, enhancing solvent recovery and minimizing loss.
