4.2 PROGRAM 2 . Wrapped Instruments and Porous Loads
For wrapped instruments and materials, when the manufacturer
recommends autoclaving at temperature of 121°C (250°F) with a drying
stage.
Nominal parameters default settings
♦ Sterilization temperature: 121°C (250°F)
♦ Sterilization time: 15 minutes
♦ Dry time: Models EA − 30 minutes.
Models E/EK − 60 minutes.
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 4 psi abs. (124 kpa abs.).
♦ Dry heating of chamber to remove leftover moisture from the
instruments and wraps, 30 minutes for models EA and 60 minutes for
models E/EK.
