Disinfection is a process that reduces the number of microorganisms to a level at which they do not present a risk to patients or clients. It is only effective if surfaces and equipment have been cleaned thoroughly with detergent and water beforehand.
What are the 3 types of sterilization?
- Plasma Gas Sterilizers. ...
- Autoclaves. ...
- Vaporized Hydrogen Peroxide Sterilizers.
What is the best method of sterilization Why?
The laboratory sterilization method of choice in most labs is autoclaving : using pressurized steam to heat the material to be sterilized. This is a very effective method that kills all microbes, spores, and viruses, although, for some specific bugs, especially high temperatures or incubation times are required.
Do you sanitize or disinfect first?
Remember that you should disinfect – not sanitize – because disinfectants are the only products approved by the EPA to kill viruses on hard surfaces.
What is the difference between sterilization and disinfection?
Sterilization describes a process that destroys or eliminates all forms of microbial life and is carried out in health-care facilities by physical or chemical methods. ... Disinfection describes a process that eliminates many or all pathogenic microorganisms , except bacterial spores, on inanimate objects (Tables 1 and 2).
What is the difference between disinfectant and sanitizer?

What are the types of disinfection?
Disinfectants can be split into two broad groups, oxidizing and nonoxidizing . Oxidizing disinfectants include the halogens, chlorine, iodine, bromine, and chlorine dioxide, and oxygen-releasing materials such as peracetic acid and hydrogen peroxide.

Is autoclaving a form of sterilization?
Autoclave sterilization works by using heat to kill microorganisms such as bacteria and spores . ... According to Centers for Disease Control (CDC) Guidelines for Disinfection and Sterilization of Healthcare Facilities, pressurized steam is the most widely used and dependable method of sterilization.
Why is autoclaving the most effective way of sterilization?
Autoclaving is the most effective method of sterilizing the lab equipment specially for liquid handling products to kill harmful bacteria, viruses, fungi, and spores. The autoclaving process takes advantage of the phenomenon that the boiling point of water (or steam) increases when it is under high pressure .
