We present a modular centrifugal micromixer comprising a mixing unit hosting a planar network of low-aspect-ratio micro-fluidic channels ("disk"), a fixed rotating drive ("player") and contact-free dispensers for the continuous feed of educts. The modular setup allows a simple fabrication and a child's play exchange of the mixing unit. High-speed micromixing is powered by the Coriolis force at volume throughputs of up to milliliters per minute and microchannel! These outstanding characteristics are demonstrated by experiments and accompanying CFD-simulations.
