4 STERILIZATION PROGRAMS
The autoclave offers 6 sterilization programs without drying +1 test program.
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
134
ºC.
Nominal Parameters
 Sterilization temperature: 134ºC (273ºF)
 Sterilization time: 3 mins.
Operations Sequence
 Heating phase; water enters the chamber and warms up until the
sterilization temperature is reached.
 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.
