The Short Path Evaporator SPE is an Agitated Thin Film Evaporator TFE/P with a built-in condenser in the evaporation chamber, mounted coaxially to the rotor, which results in a very short distance between the heating and condensing surfaces.
The Short Path Evaporator SPE is the best solution for molecular distillation and purification of extremely heat-sensitive substances and products with very high boiling point, under extreme vacuum conditions. For this type of applications, the pressure drop of the external condenser would be unacceptable.
In a multi-stage system, Short Path Evaporators can be used as final stage in combination with a Thin Film Evaporators .
