Full Answer

Steam sterilization occurs under high pressure to increase the temperature and ensure all bacteria are killed. Sterilization occurs after equipment is exposed to a minimum of 15 minutes of steam at 250 degrees Fahrenheit.

Another common low temperature technique is the use of ethylene oxide, which is pumped into a sterilization chamber with equipment inside. This sterilization process takes up to 18 hours.

Other sterilization techniques include the use of ozone gas, formaldehyde gas, microwaves or ionizing radiation.
