Abstract
A device for analyzing the metabolism of cells includes a supporting base which carries a pH measuring electrode, a control electrode designed for proton exchange with the liquid, a reference electrode, and a counterelectrode, and which, together with at least one other part, confines a hollow space containing the cells and a liquid. The electrodes are connected to electronic circuit elements. In the course of an analysis the pH value of the liquid is determined by means of the pH measuring electrode and the reference electrode. Between the control electrode and the counterelectrode an electric current is passed through the liquid and controlled such that the pH of the liquid is maintained at a constant preset value beneficial to the cells, by proton exchange with the control electrode. In addition, the amount of charge required for generating the current during the measuring period is determined to obtain a measure for the intensity of the metabolic process and thus for the vitality of the cells.
