The rotating flask generates an effective heat transfer for fast evaporation preventing a local overheating whilst leading to a smooth mixing of the content. It’s the easy to operate rotary evaporator model with motor lift for all standard applications: reliable, easy to maintain. This is an ideal evaporation instrument for your laboratories.


  • 2-stage triple-coil condenser design with extra large cooling surface for outstanding cooling efficiency.
  • Excellent handling by large and easy readable LCD display of temperature of bath and rotation speed of rotary flask.
  • Upgraded automatization, automatically adjusting the height of the bath by motor lift.
  • Sealing parts are flange with PTFE, which can keep the whole system with high vacuum.
  • Professional modular design and can be customized by clients’ requirements.
