Where is the rotation speed displayed?

The rotation speed, as well as heating bath temperature and lift position, are shown on the integrated bath display. When using an interface those parameters are shown on both the bath and the interface.

Why should I buy plastic coated glassware?

How do I determine the optimum evaporation conditions?





  • 50 °C heating bath temperature
  • 30 °C boiling temperature (by adjusting the vacuum)
  • < 10 °C cooling temperature


  • No risk of scalding when handling the evaporation flask
  • Lower evaporation of heating liquid (e.g. water)
  • Higher energy efficiency compared to other heating bath temperatures

Is the selection of the right condenser important?


Which liquid should be used in the heating bath?


Can I reduce the energy consumption of the evaporation system?

Yes, the ECO-mode is an integral part of the BUCHI Rotavapor R-300 system. Both bath and chiller enter a stand-by more after a pre-defined period of time and are restarted automatically when required.

Why are there some condensate droplets on the diaphragm?

If the distillation parameters are not chosen according to the "delta 20 rule" (10-30-50), the condensation is not complete and vapor is entering into the pump. Due to the high vacuum in the second stage, the vapor may condensate, leading to droplets. Thus, the pressure has to be increased or the cooling temperature of the condensation assembly decreased.
