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.
