Abstract: A valve setup for SMB chromatography includes a cassette block, a control block, a swiveling door, and a flexible pressurizing tube. The cassette block is configured to control each of a plurality of valves when an operation surface is in close contact with a control surface of the cassette block. The swiveling door is hinged to the valve control block such that an open state of the door arranges the cassette block such that the control surface is at the operation surface of the control block, and a closed position holds the cassette block with an inner surface of the swiveling door abutting a rear surface of the cassette block opposite the control surface. The flexible pressurizing tube is arranged at the inner surface of the swiveling door so the pressurizing tube presses against the rear surface of the cassette block when the pressure in the tube is increased.

Abstract: Determining optimum operating binding capacity for a MCC process using one column, the process including N number of columns, comprises loading target product on a first column at a first residence time and/or flow rate; loading the product on the column at a second residence time and/or flow rate, the first residence time and/or flow rate being different than the second residence time and/or flow rate; generating a first breakthrough curve for the first residence time and/or flow rate and a second breakthrough curve for the second residence time and/or flow rate, wherein the first curve represents product breakthrough for the first column and the second curve represents product breakthrough for an Nth column; and using the curves to determine product loading capacity of the first column before product breakthrough at the Nth column; the product loading capacity of the first column equaling optimum operating binding capacity for the process.

Abstract: An assembly is provided that comprises: a valve cassette block (20) comprising a plurality of valves (25) which are controllable via a control surface (24) of the valve cassette block (20); a valve control block (10) having an operation surface (11), the valve control block (10) being configured to control each of the plurality of valves when the operation surface (11) is in close contact with the control surface (24) of the valve cassette block (20) in an operation position; at least one swiveling door (30) hinged to the valve control block (20) such that an open state of the swiveling door (30) allows arranging the valve cassette block (20) into the operation position with its control surface (24) arranged at the operation surface (11) of the valve control block, while a closed position of the swiveling door (30) is configured to hold the valve cassette block (20) in the operation position with an inner surface of the swiveling door (30) abutting a rear surface (26) of the valve cassette block (20) oppos
