What is Chemical Sterilization?


All laboratories and hospitals are required to sterilize their custom procedure trays, this is because viruses, fungi, bacteria and other disease causing agents cannot be eliminated totally by just disinfecting the area where medical procedures are carried out. What disinfection does is to remove the agents and does not kill them.

al halogens that are currently in use, they include iodine, chlorine and their derivatives. They are used to kill spores and have a general microbicidal effect.

Iodine on the hand has effects that resemble those of chlorine and is mostly used to disinfect wounds and skin.

  • Oxidants- Oxidants that are used in disinfection include hydrogen peroxide, ozone, peracetic acid, and potassium permanganate. Their mode of action is based on splitting off of oxygen. They are used in mild antiseptics to disinfect custom procedure trays or skin before an operation.
  • Surfactants- These are surface-active agents whose efficacy is good with Gram-positive bacteria therefore making their bactericidal only moderate. The advantage that comes with using surfactants on custom procedure trays is their lack of odor and their good skin tolerance.
