Sterilization
Procedures
AMO recommends that you follow the sterilization procedures outlined in this
section to maximize the life of your System instruments.
All parts must be cleaned thoroughly prior to sterilization, and all sterilization
equipment must be validated prior to use.
CAUTION: DO NOT STERILIZE THE HANDPIECES PRIOR TO
PERFORMING THE CLEANING PROCEDURES DESCRIBED EARLIER
IN THIS SECTION.
THE STORAGE CASES PROVIDED CANNOT BE PLACED IN AN
AUTOCLAVE.
The following sterilization techniques, times, and temperatures must be used in
order to ensure consistent product performance:
Gravity Displacement Sterilization – A type of sterilizer in which incoming steam
displaces the residual air through a port or drain usually in or near the bottom of the
sterilizer chamber. Typical operating temperatures are 121 to 123°C (250 to 254°F)
and 132 to 135°C (270 to 275°F).
Prevacuum Sterilization – A type of sterilizer which relies on one or more pressure
and vacuum excursions at the beginning or end of the cycle.
This method of operation usually results in shorter cycle times because of the rapid
removal of air from the chamber and the load by the vacuum system, the usually
higher operating temperature (132 to 135°C / 270 to 275°F; 141 to 144°C / 285 to
290°F), and the shorter exposure time for porous loads.
Note: The cycle times require the product to be wrapped. In an emergency
situation only Flash Sterilization in accordance with ANSI/AAMI
ST79:2006 Comprehensive guide to steam sterilization and sterility
assurance in health care facilities can be used. The parameters for mixed
porous and nonporous items must be used.
CAUTION: GAS STERILIZATION IS NOT RECOMMENDED.
Cooling is not necessary prior to reassembly; however, caution must be used to
prevent burns. Follow the handpiece assembly instructions.
