TruFluor DO – Preliminary Single Use Optical Dissolved Oxygen Probe

Finesse Solutions

The TruFluor™ dissolved oxygen and temperature sensor is a single-use solution consisting of a disposable sheath, an optical reader, and a transmitter.

The single-use sheath can be pre-inserted in a disposable bioreactor bag port and irradiated with the bag, in order to both preserve and guarantee the sterile barrier. All wetted materials of the sheath are USP class VI compliant.

The optical reader utlises an LED and a large area photodiode with integrated optical filtering, that minimises photo-degradation of the acting sensing element. The design has been optimised to provide accurate in-situ measurement of dissolved oxygen using phase fluorometric detection in real time. The temperature measurement leverages a 316L stainless steel thermal window embedded in the sheath, and provides a highly accurate temperature measurement that can be used as a process variable.

Features:

  • Sheath, optical reader and transmitter
  • Excellent precision and accuracy
  • RFID tagging for self-calibration and lot traceability
  • USP Class VI, gamma radiation resistant wetted materials
  • Plug-and-play
