Instruments which undergo sterilization are first immersed in an Ultrasonic, a device which uses cleaning solution and vibrations to shake any debris from the instruments. Next, each instrument is individually wrapped in sterilization packing and subjected to a Cold Sterilization Tank or an Autoclave, depending on instrument type. The Autoclave sterilizes with heated steam under pressure, reaching or exceeding 273ºF. (For reference, the boiling point of water is 212ºF.) Finally, all instruments are then stored in sterile cupboards until their use is again required.
