The process according to the present invention allows the preparation of well-defined Ot highly concentrated formulations containing biomolecules, particularly proteins, intended for pharmaceutical or non-pharmaceutical 1-1 c:::: , use. Unwanted excipient(s) of the starting liquid biomolecule formulation, may be reduced under solution conditions, to very low levels N or levels lower than the detection limit. C
