Flow-Cell Probes

Polestar’s flow-cell probe is a zero dead-volume sensor that can be used with Polestar’s DSP series optical process monitors for continuous measurement of O2, pH, or CO2. Pre-calibrated O2-, pH-, or CO2-fluorescent sensing films are deposited along the inner surface of the quartz flow-cell body, enabling optical interrogation through the transparent wall of the flow-cell via Polestar’s standard fiber optic cable. A simple, re-useable clamping device with integral fiber optic connector is provided to facilitate mounting the device. Flexible silicone tubing on each end of the flow-cell enables quick connection to external tubing or adapters, such as Luer-Lock fittings. All materials used in the construction of the flow-cell sensors are USP Class VI certified and can withstand autoclave or gamma sterilization.
