A novel micro peristaltic pump with two separate parts is presented. One part of the pump was integrated into a small disposable cartridge and the other was made reusable as an integrated part in the analytical device. Regarding the first part, three identical chambers were fabricated in the cartridge and actuated in peristaltic mode by strong permanent magnetic forces as well as restoring forces. The peristaltic timing was generated by the second part which is a reusable rotating permanent sector magnet. A maximal flow rate of 3.1 mL/min and backpressure of 20 kPa were achieved with this pump.
