Chemical sterilization is one of the frequently used methods of sterilization in the laboratory and the entire hospital. The ways which chemical are used for sterilization depend on the strength and effect the chemical has on the micro organism. Chemical use for sterilization is expected to have potential to change the physical and chemical nature of the substance of micro organism. Bellow is different chemical methods used to achieve sterilization;
Indicator: this is used to differentiate the products which have been treated with the one which is not treated. The indicator has black strip these are seen after sterilization by using hot air steam or ethylene oxide for the sterilization.
Bowis Indicator: these examine the performance of vacuum autoclave when sterilizing porous loads.
Temperature specific Indicator: these are inserted in the middle of pack load to confirm if the load has been autoclave to a desired temperature, but not inclusive to determine the length of time that the load was at a desire temperature.
Multi parameter indicator: these work in conjunction of a joined action, it used to differentiate the constituent of the killing process which are the time which sterilization process last, and heat in the autoclave, Example of such material are Brownes sterilization control tube and thermolog. This material work by changing of color, the color change from red to green when the desired combination temperature time is ascertained.
