What are the physical and chemical methods of sterilization?

Chemical Methods of Sterilization:

Chemicals can act as disinfectants to destroy pathogenic bacteria from the upper surface. – Liquid- chemical method of sterilization involves the application of liquid to destroy the microbes permanently. – Alcohols– usually, 70% of alcohols are used as a chemical to kill bacteria.

What are the 4 methods of sterilization?

Classical sterilization techniques using saturated steam under pressure or hot air are the most reliable and should be used whenever possible. Other sterilization methods include filtration, ionizing radiation (gamma and electron-beam radiation), and gas (ethylene oxide, formaldehyde).

What are physical methods?

Physical Methods: (IGC) is a bottom-up approach to synthesize nanostructured materials, which involves two basic steps. The first step is the evaporation of the material and the second step involves a rapid controlled condensation to produce the required particle size.

What is the most effective physical method for sterilization?

The autoclave is still considered the most effective method of sterilization. Outside laboratory and clinical settings, large industrial autoclaves called retorts allow for moist-heat sterilization on a large scale.

What are 3 types of sterilization?

Three primary methods of medical sterilization occur from high temperature/pressure and chemical processes.

• Plasma Gas Sterilizers. ...
• Autoclaves. ...
• Vaporized Hydrogen Peroxide Sterilizers.

What is chemical method of sterilization?

Hydrogen peroxide is a liquid chemical sterilizing agent which is a strong oxidant and can destroy a wide range of microorganisms. It is useful in the sterilization of heat or temperature-sensitive equipment like endoscopes. In medical applications, a higher concentration (35-90%) is used.
