A process for purifying a liquid feedstock comprising a monoclonal antibody and impurities, the process comprising passing the liquid feedstock through an apparatus comprising at least two processing units, each such unit producing a product stream containing purified monoclonal antibody and optionally a waste stream comprising at least some of the impurities, wherein each unit comprises specified components (i) to (v) which include a multiple inlet flow-controller comprising two or more variable flow inlet valves for in situ production of a bioprocessing liquid by combining at least two liquids in a desired ratio. One of the units performs chromatography and another performs viral inactivation. The units may be essentially the same except for a device they contain, leading to advantages in terms of simplicity, cost and ease of operation, lower risk of operator error, easier maintenance and lower inventory of spare parts.
