Finesse Demonstrates TruFluor(TM) pH, a Single-Use Optical pH Sensor and Transmitter

SANTA CLARA, Calif., March 6 /PRNewswire/ -- Finesse Solutions, LLC, Santa Clara, CA, a manufacturer of measurement and control solutions for life sciences process applications, announced the technical demonstration of TruFluor(TM) pH, a single use optical pH measurement system, at Interphex in New York on March 17, 2009.

The TruFluor pH 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 uses advanced optical components including a large area photodiode that minimizes photo-degradation of the active sensing element. Similar to its dissolved oxygen counterpart, the TruFluor pH design has been optimized to provide accurate, in-situ measurement of pH 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.

The TruFluor(TM) pH Transmitter optimizes the performance and reliability of the TruFluor pH Sensor, by enabling automatic entry of calibration and traceability data using RFID, diagnostics, and verification. The calibration and lot data are encoded on a gamma radiation resistant tagging of disposable sheath. The RFID data is automatically read by the transmitter, thereby eliminating the need to calibrate the probe and minimizing error and variability in the calibration.

"TruFluor pH completes our single-use sensor offering. This product is optimized for accuracy, lifetime, and ease of use. We anticipate that the TruFluor sensor family will provide a unique, complete solution for single-use bio-processing applications," stated Finesse Solutions' CTO, Dr. Mark Selker.
