1. A digital microfluidics apparatus, the apparatus comprising:
a seating surface configured to concurrently seat one or more cartridges;
a plurality of drive electrodes disposed on the seating surface, wherein the drive electrodes are configured to apply a voltage to move a droplet within one or more cartridges seated on the seating surface;
a plurality of vacuum ports distributed across the seating surface;
a vacuum control configured to selectively apply vacuum through a subset of the plurality of vacuum ports under the one or more cartridges seated on the seating surface;
an electrical control for applying energy to the drive electrodes to move a droplet within an air gap of the one or more cartridges seated on the seating surface; and
a liquid handling subsystem for dispensing or removing liquid to the one or more cartridges.
