All vapour molecules reach the surface of the condenser without colliding with other molecules and thus returning to the liquid. The operation pressure of 0.001 mbar (a) and the distance between heating surface and condenser in Buss-SMS-Canzler short path evaporators provide ideal conditions to allow the molecular distillation.

Molecular distillation occurs at low temperatures and reduces the problem of thermal decomposition. High vacuum also eliminates oxidation that might occur in the presence of air. The rate of evaporation is controlled by the rate at which the molecules escape from the free surface of the liquid and condense on the condenser. The effects of feed ...
