Page 36: Information On Choosing Distillation Conditions
BÜCHI Vacuum Controller V-800/V-805 9 Distillation conditions Information on choosing distillation conditions To achieve optimum distillation conditions when rotary evaporators are used, the energy, supplied for distillation from ∆T the heating bath, must be removed via the condenser. To (min. 20°C) guarantee this, operations should be performed according to this rule of thumb.
