Molecular distillation equipment

Molecular Distillation is a special liquid-liquid separation technology, which is different from traditional distillation on the difference boiling point. This is a kind of distillation in high vacuum environment, for the difference of material molecular movement free path, was carried out in the heat sensitive material or high boiling point material distillation and purification process. Short Path Distillation is mainly used in chemical, pharmaceutical, petrochemical, spices, plastics,oil and other fields.


Also supports L/C,D/A,D/P,T/T,Western Union,MoneyGram payments for offline orders.



High evaporation efficiency and reduced retention time, with minimal time delay

Molecular distillation is made from 3.3 high borosilicate glass and PTFE, which have excellent corrosion resistance

Main body of molecular distillation is made of 3.3 high borosilicate glass , allowing the whole process to be observed very clearly

High-precision distillation barrel allows the liquid to form a complete and unified thin film on the heated surface. The smooth inner surface, avoid stick and scaling

Frequency conversion deceleration motor, with self-cooling fan,long time continuous working

Magnetic force transmission make film forming system separate from motor, the top sealing of distillation barrel have no dwang through. The whole System performs a completed sealing. The minimum vacuum pressure is up to 0.1Pa.
