CHEMICAL AGENT PROCEDURE FOR STERILIZATION IN THE LABORATORY

There are several chemical agent is used for disinfection. Disinfectant is a chemical substance that destroyed micro organism in an inanimate object. The chemical agent that kill germs or inhibit it growth is called germitocide. While the chemical agent that kill the growth of bacterial is called bactericide.

A chemical that is used to kill or inhibit the growth of micro organism in human body without the chemical poses any effect to the body tissue is called antiseptic.

While chemical agent used to prevent organism to growth in a culture media but does not kill the organism is called bacteriostatic

They way which these chemical substance works are change by many different factor. Some chemical are very powerful in the present of organic material while some are less powerful in the present of these material. Chemical substance work as sterilizing agent by the way which they kill organism i.e;

1. Destruction of the organism cell membrane
2. Interference with enzyme of the organism called poison
3.  Coagulate their protein
4. Oxidation process

There are varieties of chemical substance used for disinfectant, but few once will be our major focus, such are those one that are very essential in the laboratory
