Rosemount™ 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 a Single-Use bag.
Only the gamma-irradiated adapter touches the process solution, meaning the sensor can be reused for multiple batches. The 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.

Features

  • Sensor window compatible with standard dissolved oxygen sensors without reducing measurement performance
  • Adapts sensors designed for stainless steel bioreactors into Single-Use bags
  • Adapter arrives installed and gamma-irradiated with the Single-Use bioreactor bag
  • Membrane allows for up to 10 psi without a sensor supporting, and up to 30 psi with the sensor in place
  • Compatible with 120 mm sensor with a PG13.5 process connector
  • All wetted materials are are USP Class VI, ADI-free, and chosen for minimal extractables
  • Reuse dissovled oxygen sensor across multiple batches without autoclaving as it does not contact process solutions
  • Optimized for use with Rosemount Hx438 dissolved oxygen sensor and Rosemount 56 transmitter for software compatibility
  • Rosemount 550DW has a shelf life of two years
