Abstract:
1. A method for high-precision separation of pharmaceutical or biotechnology liquids by direct flow filtration, comprising: providing within a reservoir a pharmaceutical or biotechnology liquid having target bio-molecules dissolved or suspended within a carrier liquid; controlling movement of the pharmaceutical or biotechnology liquid within a flow path which includes moving the liquid from the reservoir to a direct flow filtration separation unit having an inlet and an outlet; monitoring pressure at a location along the flow path; passing the liquid containing target bio-molecules through the inlet of the direct flow filtration separation unit to separate at least some of the target bio-molecules therefrom; controlling movement of the liquid containing target bio-molecules to the separation unit, said controlling movement including: collecting target bio-molecules as a purified pharmaceutical or biotechnology product of purified target bio-molecules by separating same from the carrier liquid and undesirable contaminants.
