  • Page 27: Choosing Distillation Conditions

    BÜCHI Rotavapor R-200/205 5 Operation Choosing distillation conditions To achieve optimum distillation conditions when rotary evapo- rators are used, the energy, supplied for distillation from the heating bath, must be removed via the condenser. To guaran- tee this, operations should be performed according to this rule of thumb.
  • Page 28 BÜCHI Rotavapor R-200/205 5 Operation There are basically two possibilities for optimising distillation: 1. Slowly reduce pressure again Bath must have reached 60 °C (Boiling point is reduced, increase of ΔT1, resulting in increase of distillation capacity) 2. increasing bath temperature (Increase of ΔT1, resulting in increase of distillation capacity).
