• a movable door movable between an open and a closed position, said movable door having a perimeter;
• a circuit comprising a plurality of connectors and a network having conduits for conveying liquid between said connectors, which circuit comprises a bag comprising two flexible films and said connectors, which circuit further comprises a press comprising a first shell disposed upright on said front face of said base and a second shell mountable on said first shell, said first shell and second shell cooperating with said bag to form, between said flexible films, by clamping of said bag between said first shell and said second shell, the conduits of said network;
• a hinge system hinging said door relative to said base, said hinge system being disposed only on one side of said door so as to form, in the closed door position, lateral clearance between the door and the base over the rest of the perimeter of the door, so as to enable free access to the connectors.
