(recommended for clinical material). And for 120-126º C it will range between 15-20 minutes, referring to the “plateau” time. In other words, the sterilization time will start counting when the temperature is homogeneous throughout the chamber, so the total duration of the cycle will be longer, between 45-60 minutes.
