SciPres Sensor Autoclave Test Protocols
Parker/SciLog DN 3127: SciPres Pressure Sensor, Post Autoclaving Sensor Response.
Objective: Test SciPres Sensor Response after Repeated (3) Autoclaving Cycles. Autoclaving
Conditions: Sterilization Temperature: 257ºF (125ºC); Sterilization Time: 30min., Pressure: 19 psi,
Drying Time: 30min.
For accurate performance, sensors should not be autoclaved more than two times.

Test Protocol: Prior to autoclaving, factory-calibrated SciPres sensors (6) were removed from inventory and
pressure-tested at 0.00 and 30.00 psi. The "out-of-box" sensor response data are listed as "Pre-Autoclave" in the
table above. The SciPres sensor ambient air-vent as well as the 8-pin sensor connector were covered with
autoclavable tape (Cole-Parmer P/N: EG-08277-62). The sensors were placed into a paper bag (6 1/2"x 4" x12
3/8"), sealed with tape and placed in a Tuttnauer EZ9 Autoclave. The following conditions were maintained
throughout the three autoclaving trials: 1.Sterilization Temperature: 257ºF (125 ºC); 2.Sterilization Time: 30 min;
3.Sterilization Pressure: 19 psi, 4.Drying Time 30 min.
After each trial, the SciPres sensors were allowed to cool to room temperature for one hour, followed by pressure
tests at 0.00 psi and at 30.00psi. The applied pressure (30 psi) was generated with a regulated nitrogen gas
source while monitoring the applied pressure with a NIST-traceable pressure gauge. The SciPres sensor
response data (displayed by the SciPres Monitor) are listed in the table above as "Post-Trial 1", "Post-Trial 2" and
"Post-Trial 3".
Post-autoclave sensor response tests were carried out with the original factory calibration. No sensor re-
calibrations were made before, during or after the three trials.
Summary: The tested SciPres sensors survived the autoclave conditions. However, sensor accuracy becomes
increasingly compromised after multiple autoclave cycles. For accurate performance, sensors should not be
autoclaved more than two times.
NOTE: Parker sensors have been designed for disposable, single-use applications. However, with
proper care, the sensors can be re-used while maintaining good accuracy and precision. If required,
sensors can be re-calibrated. CAUTION: Do Not Exceed Maximum Pressure of 60 psi
