Calibration of the oxygen and pH sensors in five different micro-pockets on the same lid. (a) Stern-Volmer graph for oxygen sensor calibration shows a linear response to increasing oxygen concentration. The oxygen sensor was calibrated in DMEM medium purged with a gas mixture containing varying oxygen concentration. (b) pH sensor calibration with Boltzmann curve fitting. The sensor response in a pH range of 6.7–8.2 (black vertical lines) can be approximated as linear. The calibration was performed in a series of Britton-Robinson buffers with differing pH values.
