How many sterilization methods are there?

The sterilization methods series can help you make an informed decision. It includes 12 blog posts and covers 9 different sterilization methods that can be divided into two major categories: heat and non-heat sterilization methods.

Which sterilization method is best?

Steam is one of the most popular sterilization methods. In most cases, the item that requires sterilization is placed in an autoclave or similar chamber. The combination of water vapor, high temperatures, pressure, and time destroy the microorganisms.

What is sterilization and its importance?

Sterilization is the process that kills all forms of bacteria, disease, fungi, and viruses. Disinfection procedures before and after a medical event prevent the transmission of germs. Not only will it protect the patients, but also the medical professional.

Who introduced sterilization techniques?

Two major contributions to the art of sterilization came in the 1860’s when the French chemist and microbiologist Louis Pasteur wrote extensively on how germs cause disease and the English physician, Joseph Lister, developed a technique that used carbolic acid as a spray to disinfect instruments.

What is irradiation sterilization?

Food sterilization by gamma irradiation is the process of exposing food to ionizing radiation to destroy microorganisms, namely bacteria, or insects that might be present in the food.

What is the temperature of autoclave?

Autoclaves use saturated steam under pressure of approximately 15 pounds per square inch to achieve a chamber temperature of at least 250°F (121°C) for a prescribed time—usually 30–60 minutes.

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 are the main types of sterilization?

  • Steam Sterilization.
  • Flash Sterilization.
  • Low-Temperature Sterilization Technologies.
  • Ethylene Oxide “Gas” Sterilization.
  • Hydrogen Peroxide Gas Plasma.
  • Peracetic Acid Sterilization.
  • Microbicidal Activity of Low-Temperature Sterilization Technologies.
  • Bioburden of Surgical Devices.

What are the advantages and disadvantages sterilization?

Advantages of dry heat sterilization are that it’s inexpensive, it doesn’t pollute or cause toxic fumes, and it doesn’t corrode or rust metal objects. Disadvantages are that it’s relatively slow and that many objects can’t withstand the high temperatures.

What is irradiation used for?

Irradiation is a technique used in food production. It can be used to kill bacteria that cause food poisoning, such as salmonella, campylobacter and E. Coli. It also helps to preserve food and reduce food waste.

What is irradiation process?

Irradiation is the process by which an object is exposed to radiation. … Most frequently the term refers to ionizing radiation, and to a level of radiation that will serve a specific purpose, rather than radiation exposure to normal levels of background radiation.

What is meant by gamma irradiation?

Gamma irradiation is exposure to ionizing radiation with gamma rays. It may also refer to the following processes in particular: Ionizing radiation sterilization. Food irradiation. Gamma knife, used in radiosurgery.
