4 STERILIZATION PROGRAMS
The autoclave offers 6 sterilization programs, with or without drying
stage.
4.1 Program 1 – Unwrapped Instruments (1 – Instruments)
Program 1 is recommended for sterilizing unwrapped instruments and
materials for immediate use and preventing cross infection at temperature
134ºC. No drying is required.
Nominal Parameters
 Sterilization temperature: 134ºC (273ºF).
 Sterilization time: 3 minutes.
Operations Sequence
 Heating phase; water enters the chamber and is heated until the
sterilization temperature is reached.
 Sterilization phase; temperature is maintained constant at the preset
value for the sterilization time.
 Fast exhaust phase (Ex. Mode=1); steam is rapidly exhausted from the
chamber, until pressure equalizes to atmospheric pressure.
Note:
The sterility of instruments processed in unwrapped cycles
cannot be maintained if exposed to non-sterile environment.
