What is the purpose of the sterilizer?
Sterilization destroys all microorganisms on the surface of an article or in a fluid to prevent disease transmission associated with the use of that item.
What is sterilization and its methods?
Sterilization can be achieved through various means, including heat, chemicals, irradiation, high pressure, and filtration. Sterilization is distinct from disinfection, sanitization, and pasteurization, in that those methods reduce rather than eliminate all forms of life and biological agents present.
How does a sterilizer work?
Autoclave sterilization works by using heat to kill microorganisms such as bacteria and spores. The heat is delivered by pressurized steam. It’s nontoxic and inexpensive, it kills microbes and spores rapidly, and it quickly heats and penetrates fabrics.
What are the 2 methods of sterilization?
Different sterilization methods used in the laboratory
- Heat Method: This is the most common method of sterilization.
- Filtration is the quickest way to sterilize solutions without heating.
- Radiation sterilization: This method involves exposing the packed materials to radiation (UV, X-rays, gamma rays) for sterilization.
