4.2 PROGRAM 2. Wrapped Instruments and Porous Loads
For wrapped instruments and materials, when the manufacturer
recommends autoclaving at temperatures between 250°F and 274°F
(121°C and 134°C) with a drying stage.
Nominal parameters default settings
♦ Sterilization temperature: 273°F (134°C).
♦ Sterilization time: 7 minutes.
♦ Dry time: 30 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 and forced air circulation for 30 minutes to remove
leftover moisture from the instruments and wraps.
