Short path distillation is a process in which one separates compounds via boiling/condensation using a vacuum pump. By adding a vacuum to remove the atmospheric pressure inside the system. When the pressure is lowered, the boiling points of the contained compounds will go down. This process makes it faster and more efficient to distill heavier molecules. It is designed according to the principle of molecular distillation. Typical applications are polymer organic compounds and thermal sensitive products, particularly from the chemical and food industries, because the high boiling points, lab usually choose the heating mantle to distillation.
