3 STERILIZATION PROGRAMS
The autoclave offers 4 sterilization programs, with or without a drying stage and
2 test programs.
3.1 Program 1 - Unwrapped Instruments (1 - Flash 273)
Program 1 is recommended for a single unwrapped instrument and other
materials intended for immediate use and for the prevention of cross
contamination, when the manufacturer recommends autoclaving at
temperatures of 273ºF (no drying cycle is required).
Nominal Parameters
♦ Sterilization temperature: 273ºF - 279ºF.
♦ Sterilization time: 3.5 minutes.
Operations Sequence
♦ Pre Vacuum stage; two vacuum pulses remove air by drawing the
chamber down to –11.8 psig (24 Ih). At the end of the pre vacuum
stage steam enters the chamber from the jacket until the sterilization
temperature and pressure is reached.
♦ Sterilization stage; temperature and pressure are maintained
constant at the preset level for the programmed sterilization time by
periodic injection of steam from the jacket.
♦ Exhaust stage; steam is rapidly exhausted from the chamber
allowing the chamber pressure to reach 0 psig (atmospheric
pressure).
Note:
The sterility of instruments processed in unwrapped cycles cannot be
maintained if exposed to non-sterile environment.
