The pH of a cell culture media can be maintained constant by controlled addition of gaseous carbon dioxide (CO2). The MASSFLOW is ideal for this purpose.
Connect the CO2 gas tubing to the MASSFLOW and to the gas inlet of the bioreactor. Plug the remote control cable of the MASSFLOW to the pump socket (ACID) in the rear side of MINIFOR laboratory-scale bioreactor. Press the REMOTE button on the MASSFLOW and switch the flow regulator on with the ON/OFF button. The pH of the medium will be controlled automatically.
