Flow-Through Sensors

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 DO or pH. Pre-calibrated DO or pH fluorescent sensing films 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.
