The short-path distillation (molecular distillation) equipment is equipped with a inside condenser which is opposite to the heating surface, and make the operation pressure reduce to under 0.001mbar. Its relative low boiling temperature is very suitable to the material with heat sensitive and high boiling point.
application of short path distillation：Can be used in: pharmaceutical industry, chemical industry, academic/educational field, food/beverage industry, environmental analysis, etc.

What is short path distillation
In industrial and chemical fields, people always need to extract some solvents or purify some substances. There are several ways to achieve those and short path distillation is one of them. Short path distillation is a technique that removes solvents from mixtures through evaporation. Short path distillation is mainly used for liquid-liquid separation. Rotary evaporator and short path distillation are both devices for separating solvents.Short-path distillation is a device used to separate sevaral different solvents from mixtures through evaporation at the same time, while rotary evaporator is used to extract one single solvent from misture. It is widely used in cannabis oil distillation and fractional distillation of cannabinoids.
Short path distillation uses
Short path distillation is one of the most high-efficiency distillation techniques in people’s using, which can solve the problem that conventional distillation technology can’t. It is widely used in food, medicine, fine chemicals, electronic materials, plastic engineering and polymers (such as polyols, fatty acids, polyphenols, polyurethane, epoxy resins, lactic acid, monoglycerides, flavors, heavy oils and paraffin oils) and other field.
Short path distillation problems
When we use short path distillation, there are always some problems need to pay attention to, they are as follows: 1. It is essential to keep a good sealed environment, which is protective for the whole process. Because a good sealed environment can guarantee the purity of extracted solvents. 2. There is always few extracted gas solvents left in the glass reactor. Because there is a short distance from the evaporation flask to the receiving flasks. So along the distance, there is always gas solvents left.
