Molecular Distillation is a special liquid-liquid separation technology, which is different from the traditional distillation by boiling point difference separation principle, but by different substances molecular movement of the average free path difference to achieve separation. Molecular distillation is considered as the safest mode of separation and to purify the thermally unstable molecules and related compounds with low volatility and elevated boiling point.

Molecular distillation is used to distill high-value and high-purity extracts from essential oils of animals and plants, such as refined hemp oil,eaglewood, fish oil, traditional Chinese medicine, etc. Its extracts can be used as food additives, health products or medicinal raw materials.
