Hot Sale DMD Series Lab Scale 2L~20L Glass Short Path Distillation
Short Path Distillation is a distillation technique that involves the distillate travelling a short distance. It is method of separating mixtures based on differences in their volatilities in a boiling liquid mixture under reduced pressure. As the sample mixture to be purified is heated, its vapors rise a short distance into a vertical condenser where they are cooled by water. This technique is used for compounds which are unstable at high temperatures because it allows a lower boiling temperature to be used.

Glass Wiped Film Molecular Distillation Equipment
Molecular distillation is a special liquid-liquid separation technology, which is different from traditional distillation which relies on the principle of boiling point difference separation. This is a process of distillation and purification of heat-sensitive material or high boiling points material using the difference in the free path of molecular motion under high vacuum. Mainly used in chemical, pharmaceutical, petrochemical, spices, plastics and oil and other industrial fields.
The material is transferred from the feeding vessel to the main distillation jacketed evaporator. Through the rotation of the rotor and continuous heating, the material liquid is scrape into an extremely thin, turbulent liquid film, and pushed downward in a spiral shape. In the process of descent, the lighter material (with low boiling point) in the material liquid begins to vaporize, move to the internal condenser, and become liquid flowing down to the light phase receiving flask. Heavier materials (such as chlorophyll, salts, sugars, waxy, etc.) do not evaporate, instead, it flows along the inner wall of the main evaporator into the heavy phase receiving flask.

High Quality Stainless Steel Short Path Molecular Distillation Unit
Short Path Molecular Distillation is a special liquid-liquid separation technology, which is different from the traditional distillation by boiling point difference principle, but by different substances molecular movement of the average free path difference to achieve separation. So that, in the whole distillation process, material keep it’s nature and only separate different weight molecule.
When material is fed into the Wiped Film Short Path Molecular Distillation System, through the rotation of the rotor, the wipes will form a very thin film on the wall of the distiller. The smaller molecules will escape and be caught by the inner condenser firstly, and collect as Lighter Phase (Products) .While the bigger molecules flow down the wall of the distiller, and collect as Heavier Phase, which also be known as Residue.
