The Rosemount 550DW Single-Use Dissolved Oxygen Sensor Adapter is compatible with standard stainless-steel dissolved oxygen (DO) sensors, currently validated with the Rosemount Hx438 Dissolved Oxygen Sensor, and enables placement into a single-use bioreactor bag. Only the gamma-irradiated dissolved oxygen sensor adapter touches the process solution, meaning the sensor can be reused for multiple batches. The dissolved oxygen sensor adapter has a three-year shelf life and can be air-calibrated prior to start-up to verify functionality with no fill product needed in the bioreactor bag.
