    Abstract: A cartridge, in particular a disposable cartridge, for use in an electrowetting sample processing system. The cartridge has a liquid input port for introducing an input liquid into an internal gap of the cartridge, the input liquid providing for at least one droplet, directly or via a liquid separation process within the internal gap, and the internal gap having at least one hydrophobic surface, at least one processing zone for processing samples located in the processing zone, and a delivery zone for delivering the at least one droplet from the liquid input port to the at least one processing zone. The delivery zone is configured to provide a repeating pattern of interacting electrowetting force for simultaneously transporting the at least one droplet within the delivery zone.

    Abstract: Digital microfluidics system with electrodes attached to a PCB has control unit for manipulating liquid droplets by electrowetting, cartridge accommodation site for taking up a disposable cartridge having a working gap in-between two hydrophobic surfaces, and magnetic conduit/backing combination. A barrier element on an individual electrode of the PCB for narrowing the working gap. A disposable cartridge is positioned at the cartridge accommodation site, its flexible working film touching there and of the barrier element an uppermost surface. In the working gap and above a path of selected electrodes a liquid portion or liquid droplet with magnetically responsive beads moves by electrowetting on the electrode path until a magnetic field of the magnetic conduit is reached. The backing magnet is activated before and during the moving to thereby attract and remove magnetically responsive beads therefrom.
