4. STERILIZATION PROGRAMS
The autoclave offers 3 sterilization programs, at a temperatures of 121°C (250°F),
with or without a drying stage and 1 accessory (dry only) program.
A. Three sterilization programs:
1. Unwrapped instruments
2. Wrapped instruments and porous loads.
3. Liquids
B. Accessory program:
4. Dry only
Note:
The nominal data of the program (default settings) can be changed to fit the needs
or a particular office. This is done by means of the TEMP, STE.TIME, DRY
TIME, keys in combination with the UP or DN keys, as described in sec 3.2.2.
4.1 PROGRAM 1. Unwrapped Instruments
For unwrapped instruments and materials, when the manufacturer
recommends autoclaving at temperature of 121°C (250°F) no preset drying
stage required.
Nominal parameters default settings
♦ Sterilization temperature: 121°C (250°F)
♦ Sterilization time: 15 minutes.
♦ Dry time: none
Operations Sequence
♦ Heating by actuation of electrical heaters until the sterilization
temperature is reached.
♦ Sterilization temperature is maintained constant for the preset
sterilization time.
♦ Fast exhaust, steam is exhausted out of the chamber at a fast rate until
pressure drops to zero.
Note:
The sterility of instruments processed in unwrapped cycles cannot be
maintained if exposed to non-sterile environment.
