We present a novel modular micromixer based on continuous flow through rotating microchannels on a standard centrifuge. Extraordinary throughput of 1 ml / s per channel is demonstrated which can massively be enhanced to about 100 ml / s by a generic parallelization scheme. Both, experimental data and accompanying simulations demonstrate that the device outperforms other micromixers with its superior mixing quality at high throughputs. The concept furthermore excels with its simple and planar layout of low-aspect-ratio microstructures and the absence of critical micro-macro interfaces due to the field-transmitted pumping force.
