Molecular (wiped film) distillation is the best thermal separation machine for heat-sensitive material because it is the gentlest type, causing the least amount of thermal degradation of product. It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules. Lab1st molecular distillation units are wildly used for purification of oils, such as herb oil, garlic oil, cod liver oil in chemical and pharmaceutical industries.The whole molecular distillation system includes supporting chillers, heaters, vacuum pumps and all accessories.
