Wiped Film Molecular Distillation System


The Sky's The Limit

Wiped film distillation application

Molecular Distillation/Short Path Distillation is a comparatively new separation technology. It can separate liquidliquid mixture under temperature that is far lower than boiling point by the difference of mean free path of molecules under high vacuum condition. Such separation is difficult or unable to achieve on normal distillation equipments. Molecular Distillation is especially suitable to separate substances of high boiling point, heat sensitive and easy to be oxidized.

Main application field:
Food, Pharmaceutical, Fine chemical, Electronic materials, Polymers  (Polyols, fatty acids, polyphenols-compounds, polyurethane, epoxy resin, lactate, glycerol monostearate, flavors and fragrances, fuel oil and paraffin oil), etc.

Low Temperature

Distilling temperature far lower than the boiling temperature has advantages on dealing with materials that is heat sensitive, of high boiling temperature, belongs to biological acids or lipids

Short Residence Time

Heating process on material is very short. It may take only few tens of seconds to finish a separation on wiped film distillation when it takes hours on a normal evaporation apparatus.

High Vacuum Operation

high-vacuum design WFE can operate with vacuums as low as 0.001mbar. Operating at deep vacuum lowers operating temperatures and prevents thermal degradation.

Efficient and Reliable

Specially designed, effectively improve the purity of the distillate product. The system is well suited for larger extraction labs where efficiency, repeatability and ease of use are critical.
