1. A fluid control and processing system comprising:

  • a cartridge;

    a cylinder body being received in the cartridge, said cylinder body comprised of a cylinder and a fluid port in fluid communication with said cylinder;

    a piston movable in the cylinder to modulate a fluid volume inside said cylinder;

    an instrument for operating the cartridge, said instrument including;

    a piston driver for driving the piston, androtating means including a cylinder driver for rotating the cylinder body around an axis A which extends along the piston driver;

    dispensing ports to drive at least a fluid flow, each dispensing port being positioned to be connectable, when the instrument is operating the cartridge, with the fluid port by rotation of the cylinder body; and

    reversible fastening means for fastening the piston to the piston driver so that movement of the piston is controlled by the piston driver, wherein the reversible fastening means fastens the piston to the piston driver when the instrument rotates the piston driver with respect to the piston in a first direction around the axis A, and unfastens the piston from the piston driver when the instrument rotates the piston driver with respect to the piston in a second direction opposite to the first direction.
