The molecular distillation is a special liquid-liquid separation technology, which is different from traditional distillation relying on the difference between boiling points. This is a kind of process of distilling and purifying the heat sensitive material or high boiling point material by making use of the difference of material molecular movement free path in high vacuum degree. The molecular distillation is mainly used in chemical, pharmaceutical, petrochemical, spices, plastics, oil and other fields. This Molecular Distillation has the following advantages High evaporation efficiency, reducing retention time; with minimal time delay The high precision glass tube allows the liquid to form a complete integrated film on the heated surface; The MD molecular distillation system consists of borosilicate glass and PTFE and SS316L, so it has excellent corrosion resistance; The stirring motor system adopts magnetic stirring system, no noise, higher stirring speed and faster film forming speed; The squeegee film forming system is made of PTFE material and 316L, which has higher corrosion resistance; the system's maximum temperature can reach 230 C;
