Rotary Evaporator

The rotary evaporator is made according to the principle of constant temperature heating and film evaporation under vacuum and negative pressure. The rotary evaporator uses stepless speed regulation to make the glass rotating bottle rotate at a constant speed, and the materials form a large area uniform film on the bottle wall. Then, the rotating bottle is evenly heated by the intelligent constant temperature water bath, evaporated at a high speed under vacuum, and the solvent vapor is cooled by the high-efficiency glass condenser and recycled in the collection bottle. Mainly used for concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and biopharmaceutical industries.



  • Stepless speed controller
  • PID temperature adjustment
  • Automatic lift control
  • High evaporating and recovery collecting rate
