Common monitoring – one probe for all cultivations

Instead of 15 in situ probes, the monitoring of each cultivation can be accomplished with one set of flow-through probes. The flow-through probes can be connected to the sampling line enabling the measurement of pH, dissolved oxygen, redox-potential or cell density from each withdrawn sample.


For example, one flow-through OD probe provides automated real-time information of the cell density in each of the 15 cultivations losing only a few millilters of the cultivation volume. In addition, the sample can be collected after measurement and taken for further analysis.

Gas analysis

The concentrations of carbon dioxide and oxygen can be measured from the exhaust gas flow with the Gas analysis module. It enables the monitoring of all of the 15 cultivations with one pair of gas analysis probes. A stream selector valve directs the exhaust gas flow in turn from each vessel to the probes. The Controlware software application keeps a continuous log of the measurements, which can be visualized during a cultivation. The measurement range of the carbon dioxide probe is 0-10% and 0-25% for oxygen.
