Oxygen sensor FTC-PSt3

laboratoryminiature

Miniaturized chemical optical oxygen sensors integrated in flow-through cells (FTC-PSt3) allow non-invasive online monitoring of oxygen in perfusion systems. The sensors are fixed to color coded sticks, which can be attached to flow-through cells of different size and shape according to your requirements. A polymer optical fiber connects the sensor inside the flow-through cell to the respective O2 meter (e. g. Fibox 4). The FTC-PST3 cells are made of polycarbonate. Precise online monitoring of oxygen Different sizes and shapes for various flow rates Easy connection to external tubing APPLICATIONS Beta-irradiated and pre-calibrated flow-through sensors used in a bioreactor bypass Online Measurement in Perfusion Systems Beta-irradiated and pre-calibrated pH and DO flow-through sensors can be integrated into perfusion systems. This allows easy control of process parameters in perfusion reactors. Typically Luer connectors are used, though different sizes for larger or smaller flow rates are available. In-line Oxygen Monitoring in 3D Cell Culture Since oxygen has a low solubility in culture medium it must be supplied to cells within 3D scaffolds via constant perfusion of the medium. The oxygen content of the medium before and after having passed by the cells can then help to determine whether the flow rate applied is sufficient. PreSens flow-through cells with integrated chemical optical sensors can be incorporated in the construct inlet and outlet and allow in-line measurement of oxygen tension.
