NOTE: Autoclave tape does not assure sterility; the tape indicates only that the proper temperature has been achieved and is not dependent on time. They are sealed containers comes with devices that allow changing the pressure and temperature inside the chamber, as well as filtration and exhaust gas removal systems. However, not all products are easy to process in this way. For the manufacturer, it is necessary to strictly control the magnetic field distribution of the microwave to ensure uniform heating of the material; set the temperature control probe to prevent "thermal runaway" during the heating process. UV sterilization devices are more efficient to disinfect than traditional cleaning methods. Rather, static-air dry heat sterilization simply involves a heat source (usually at the bottom of the chamber) that will cause the heat to rise naturally. One type is referred to as mechanical convection, and it involves a fan that helps to circulate the heated air throughout the heated chamber (think about a convection oven that is found in many homes and restaurants).
