Abstract: A cam-driven actuator for actuating valves of a microfluidic cartridge includes a plunger associated with each valve, a plunger guide plate having a plunger guide hole for each plunger, an actuating ball associated with each plunger and in contact with the associated plunger, a ball guide plate having a ball guide hole for each actuating ball; and a cam including a first surface and a cam recess. Each actuating ball is in contact with the cam and the cam is movable with respect to each actuating ball between (i) an engaged position at which the actuating ball is in contact with the first surface and the associated plunger is in an engaged position to close the associated valve, and (ii) a disengaged position at which the actuating ball is disposed within the cam recess and the associated plunger is in a disengaged position to open the associated valve.
