A Second-Degree of Freedom Centrifugal Platform has been developed which is enabled by a differential gearing system. This system permits the rotation of fluidic chips during centrifugation controlled by two stationary stepper motors. This approach offers key advantages of low-cost, simplicity, and reliability over existing approaches which utilize complex, specialized and expensive electrical slip-rings or wireless power transfer to enable the same concept. The potential of the platform is demonstrated by implementing, using dyed water, the fluidic steps required for DNA purification.
