Customised services

With more than 20 years of experience, POLARIS offers a unique expertise (engineers and equipment) in the field of short path molecular distillation.

Molecular distillation is a continuous process under vacuum, based on the different boiling points of the molecules present in a mixture to separate them by evaporation/condensation. This physical separation method is well suited for the purification of highly heat-sensitive molecules under mild, solvent-free conditions. Short-path distillation is suitable for the fractionation of marine and vegetable oils and synthetic raw materials, to concentrate, purify, decontaminate* (*Elimination of phthalates through molecular distillation) or deodorize.


Our technological offer is adapted for lipidic substances with very high added value and for concentrations of molecules with high potential for spheres :


  • Omega 3 fatty acids
  • Monoglyceride synthesis
  • Mono-, di- and triglyceride separation
  • Oils titrated in phytosterols


  • Vegetable oils rich in unsaponifiable matter
  • Squalène
  • Olive squalane
  • Fractionated waxes


  • Fish intermediates EPA EE
  • Concentrated DHA algae EE
  • Vegetable oils (olive and soybean oils

A word from the expert

“POLARIS has a unique production tool that respects the environment, specially designed for the purification and concentration of LC PUFAs (long chain polyunsaturated fatty acids) such as EPA and DHA”

It makes it possible to reach Omega-3 (EPA/DHA) concentrations up to 3 times higher than those naturally present in fish or micro-algae oils, with EPA and DHA recovery levels close to 100%.

Polaris’ expertise in refining and molecular distillation enables it to also offer services for nutraceutical and cosmetic applications, with a multitude of processes possibilities.
