Cells for Online Oxygen Monitoring in Perfusion Systems
O2 Flow-Through Cell FTC-PSt7
A miniaturized oxygen sensor type PSt7 is integrated in a flow-through cell. It allows non-invasive online monitoring of oxygen in perfusion systems. The sensor is fixed to a color coded stick, which can be attached to flow-through cells of different size and shape according to requirements. A polymer optical fiber connects the sensor inside the flow-through cell to the respective O2 meter. The cells are made of polycarbonate.
- Precise online monitoring of oxygen
- Different sizes and shapes for various flow rates
- Easy connection to external tubing
