Cross-section scheme and function of microfluidic MTP. The two different working principles of the microfluidic process control are shown: the microvalve function applied in pH-control (A-C) and the micropump function, used for fed-batch fermentations (D-F). Filled arrows and dark gray color indicate pneumatic pressure in the pneumatic channels and the reservoir wells. Dashed arrows and black color indicate moving liquid due to the pneumatic pressure.
