ETO Gas Sterilization Procedure
When no other form of decontamination such as a germicidal wipe is acceptable, a low temperature,
(not to exceed 120°F(48.9°C)) ETO gas sterilization cycle may be used. Refer to your institution’s
standard operating procedure for the length of the cycle.
This type of sterilization may cause some hazing of glossy plastic surfaces and should be used only
when absolutely necessary.
1. Disconnect the Model 767 Thermometer from the power supply.
2. Ensure that the probe is removed from its storage channel and disconnected from the instrument.
3. Remove any probe covers from the probe cover storage well
4. Wrap the thermometer in a standard sterilization type packaging such as a Baxter Tower Dualpeel
Sterilization Pouch.
5. ETO gas sterilize at a temperature not to exceed 120°F(48.9°C) and aerate.
6. Remove the sterilization packaging.
7. Before applying power, allow the probe and instrument to stabilize to room temperature for at least
one hour.
