What is Molecular distillation and how does it work?

Short Path Molecular Distillation (Vacuum Distillation) With short path molecular distillation, the extract and solvent are placed in a centrifuge (essentially a spinning cylinder), and vacuum is pulled on the centrifuge. Heat is then applied, and the centrifugal force separates the different components allowing the extract to drain to the bottom.

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.
