550DW Single-Use Dissolved Oxygen Sensor Adapter

Rosemount 550DW single-use dissolved oxygen sensor adapter is compatible with standard stainless-steel DO sensors, currently validated with the Rosemount Hx438, and enables placement into the bioreactor single-use bag. Only the gamma-irradiated adapter touches the process solution, meaning the sensor can be reused for multiple batches. The sensor can be air-calibrated prior to start-up to verify functionality with no fill product needed in the bioreactor. Shelf life is two years.
