Installation for treating biological liquid

An installation for treating biological liquid by chromatography, generally extending in a longitudinal direction and comprising:

• at least one supply valve (20b) for supplying biological liquid to treat, configured to be connected to at least one biological liquid supply container (130);
• at least one supply pump (30) disposed downstream of said at least one supply valve and connected to the latter;
• a plurality of instrument members disposed downstream of said at least one supply pump, including at least one distribution valve (81a-c, 82a-c, 83a-c) and at least one device (78a-c, 85a-c, 86a-c) for measuring a physico-chemical parameter of the biological liquid, and which are connected to said at least one supply pump;
• at least one chromatography column (99a-c) disposed downstream of said plurality of instrument members and directly associated with and connected to at least some of them, and configured to be supplied with biological liquid by said at least one supply pump;
• and
• a plurality of single-use pipes configured to be connected to said at least one supply valve, to said at least one supply pump, to said plurality of instrument members and to said at least one chromatography column, so as to form at least one supply line (200) for supplying biological liquid to treat of a treatment circuit of said installation;
• characterized in that said instrument members associated with said at least one chromatography column are each mounted on at least one dedicated control and actuation platform (80a-c), which extends in a vertical direction relative to the longitudinal direction of extension of said installation, and are disposed above each other on said dedicated control and actuation platform;
• and
• characterized in that said distribution valves (81a-c, 82a-c, 83a-c) are each provided with a valve body and a valve head which extends from said body and which is provided to receive at least portions of pipes of said supply line, and said at least one control and actuation platform (80a-c) comprises a support block (84a-c) which extends vertically, in which are housed said valve bodies and from which said valve heads project laterally, as well as a support plate (89a-c) fastened to said support block and having an arm (191a-c) which projects from said support block and on which is mounted said at least one measuring device (78a-c, 85a-c, 86a-c).
