Where our OSN membranes can be used?


Fractionation of crude extracts

Components derived from natural extracts (from fruit, vegetables, nuts, seeds, herbs) are used in a variety of different industries, e.g. pharmaceutical, nutraceutical, flavor & fragrance, etc. due to their inherent properties and chemical diversity. Their use, however, as a crude extract often is not practical and the molecules of interest constitute only a small part of the extract. The use of Evonik’s OSN membranes with different cut-offs enables fractionation of the crude extracts according to MW or solubility of the molecules in (different) solvents and mixtures.
