SciCon Sensor Autoclave Test Protocol
Parker/SciLog DN 3130: SciCon Conductivity Sensor, Post Autoclaving Sensor
Response.
For accurate performance, SciCon sensors should not be autoclaved more than
two times.
Objective: Test SciCon Sensor Response after Repeated (4) Autoclave Cycles.
Sterilization Conditions: Sterilization Temperature; 257ºF (125ºC), Sterilization Time: 30
min. Pressure: 19psi, Drying Time: 30 min. Conductivity Test Solution: 12.99mS (KCl)

NOTE: Parker sensors have been designed for disposable, single-use applications. However, with proper care, the
sensors can be re-used repeatedly while maintaining good accuracy and precision. If required, sensors can be re-
calibrated.
CAUTION: Do Not Exceed Maximum Pressure of 60 psi
Test Protocol: Prior to autoclaving, factory-calibrated SciCon conductivity sensors (5) were removed from inventory
and tested against a conductivity solution (12.99 mS) in a temperature equilibrated glove box. The "out-of-box"
sensor response data is listed as "Pre-Autoclave" in the table above. The 8-pin sensor connectors were sealed with
autoclavable tape (Cole-Parmer P/N: EG-08277-62) The sensors were place into paper bag (6 1/2"x 4" x12 3/8") and
placed in a Tuttnauer EZ9 Autoclave. The following conditions were maintained throughout the four autoclaving trials:
1.Sterilization Temperature: 257ºF (125 ºC); 2.Sterilization Time: 30 min; 3.Sterilization Pressure: 18 psi, 4.Drying
Time 30 min. After each trial, the SciCon sensors were allowed to cool for one hour inside the temperature controlled
(25.0 ºC) glove box. 12.99 mS test solution was re-circulated through the five, in-line sensors assembly for 30 min
before reading the conductivity values. The SciCon sensor response data (displayed by the SciPres Monitor) is listed
in the table above as "Post-Trial 1", "Post-Trial 2", "Post-Trial 3" and "Post Trial 4." Post-autoclave sensor response
tests were carried out with the original factory calibration. No sensor re-calibration were made before, during or after
the three trials.
Summary: All SciCon sensors survived the four autoclave trials. However, sensor accuracy becomes increasingly
compromised after multiple autoclave cycles. For accurate performance, SciCon sensors should not be
autoclaved more than two times.
