Major pharmaceutical companies, smaller organizations, and academia have all improved their bioprocess development with PreSens sensors. Using these non-invasive measurement systems, no more time consuming sampling is necessary and they allow simultaneous monitoring of multiple samples. A wide variety of disposables with integrated, pre-calibrated sensors is available; they are ready-to-use to obtain maximum work efficiency and allow monitoring the important culture parameters O2, pH and CO2 in every step of process development.
