4.2 Program 2 (2- Instruments)
Program 2 is recommended for sterilizing unwrapped instruments and
materials for immediate use and preventing cross infection at temperatures
of 121ºC.
Nominal parameters
 Sterilization temperature: 121ºC (250ºF).
 Sterilization time: 15 mins.
Operations Sequence
 Heating phase; water enters the chamber and warms up until the
sterilization temperature is reached.
 Sterilization phase; temperature is maintained constant at the
preset level for the sterilization time.
 Fast exhaust phase (Ex Mode=1); steam is rapidly exhausted from
the chamber, until pressure equalizes atmospheric pressure.
Note:
The sterility of instruments processed in unwrapped cycles cannot
be maintained if exposed to non-sterile environment.
