TEMPRIS for Lyophilisation

TEMPRIS Sensor

TEMPRIS Features

  • wireless sensor, no battery
  • passive design, no thermal dissipation
  • real time monitoring, no logging device ("data logger") needed, data transmission via 2.4 GHz ISM band (worldwide approval), unlimited data volumes stored on remote PC
  • high accuracy, for exact monitoring of product temperature during process (+/- 1%FS)
  • sterilizable
  • sensors compliant to FDA 21 CFR Part 11
  • general PAT (Process Analysis Techniques) tool
  • easy retrofit of existing equipment possible

Special Considerations for Lyophilisation

Independent scientific research of the Freeze-Drying Focus Group (University of Erlangen, Germany) resulted in the following facts:

TEMPRIS Lyophilisation - Sensors in Vials
  • no differences in the freezing behaviour in vials equipped with TEMPRIS sensors in direct comparison with vials equipped with thermocouples
  • very flexible alternative for upgrade/replacement of thermocouples in any type of LYO chamber (up to 16 additional sensors)
  • very good correlation of the measured temperature profile during primary drying between TEMPRIS data and thermocouple data
  • very good compliance (+/-1° K) with the calculated temperature distribution over the whole product batch according to Manometric Temperature Measurements (MTM)
  • TEMPRIS shows good sensitivity for endpoint detection for primary drying because of the special geometry of the sensitive sensor apex
  • even solutions with high solid content do not affect the TEMPRIS data
  • TEMPRIS easily allows the transfer of different "edge" and "center" profiles from the laboratory equipment up to production equipment by means of identical sensors ("quick migration")
Example of a freeze-drying run monitored by TEMPRIS probes
Example of a freeze-drying run monitored by TEMPRIS probes
TC-e = thermocouple, edge vial / T-e = TEMPRIS, edge vial
TC-c = thermocouple, center vial / T-c = TEMPRIS, center vial
