Which are the most used method of sterilization?

The most used method is the sterilization by heat. According to the type of item to be sterilized, either of these two methods may be chosen:

  • Steam (autoclave);
  • Dry heat (ovens);

However, when the item to be sterilized doesn’t resist high temperatures (100ºC), the sterilization methods called ¨colds¨are used:

  • Radiations (rays gamma, ultraviolet);
  • Chemistry (gases of ethylene oxide), among others.
