There are 4 major methods for sterilization:1. Heat: Autoclaving which involves heating liquids (e.gmedia) or solids to 121°C under steam pressure. However,the materials must be heat resistant2. Ethylene oxide is sometimes used in hospitals forequipment that cannot be heated3. Membrane filters have pores that trap bacteria. but allowdrugs and small chemicals to pass through: thus pre-sterilized filters can be used to sterilize delicate solutions4. Radiation·UV light is used for decreasing bacterial levels onsurfaces such as in operating rooms; however it is nottotally effectivelonizing radiation is more efficient and can be used forsterilizing instruments and foodSHIHEZIUNIVERSITY
