ABSTRACT:
A method and apparatus for the continued incubation of cells in a liquid culture medium. When the pH value of the culture medium deviates during the incubation from a pH range suited for the growth or multiplication of the cells, the culture medium is automatically replaced. Whether or not the pH value of the culture medium has deviated from the acceptable pH range is determined by measuring the intensity of light absorbed by the culture medium.
