Program 2: Plastic
For plastic and other delicate instruments, when the manufacturer
recommends autoclaving at temperatures of 121
C (250
F).
Nominal parameters default settings
Sterilization temperature: 121
C (250
F)
Sterilization time: 15 minutes
Operations sequence:
(PV, pre-vacuum model only) Air removal stage; four vacuum pulses
removes air by drawing the chamber down to 20kPa.
Heating stage; steam enters the chamber and warms up until the
sterilization temperature is reached.
Sterilization temperature is maintained constant during the sterilization
time.
Fast exhaust, the steam is exhausted out of the chamber at a fast rate
until pressure decreases to ambient pressure.
Note:
The sterility of instruments processed in unwrapped cycles cannot be
maintained if exposed to non-sterile environment.
