What is sterilization and its types?

Common methods of sterilization include physical methods and chemical methods. Physical methods include dry heat, steam, radiation, and plasmas. Radiation encompasses a variety of types, including gamma radiation, electron beam, X-ray, ultraviolet, microwave, and white (broad spectrum) light.

What are the 2 types of sterilization?

There are two distinctive types of heat-based sterilization: Moist Heat Sterilization and Dry Heat Sterilization. Moist Heat Sterilization – This type of sterilization uses moisture, water-vapor or steam at high temperatures.

What are the types of sterilization PDF?

Moist heat sterilization involves the use of steam in the range of 121-134°C. droplets) or dry saturated steam (no entrained water droplets).
  • Dry heat Sterilisation (a) Hydrogen peroxide Sterilizer.
  • Moist heat (b) Formaldehyde Sterilizer.
  • Gas Sterilization (c) Autoclave.
  • Liquid Sterilisation (d) Hot air Oven.

What is the principle of sterilization?

The basic principle of steam sterilization, as accomplished in an autoclave, is to expose each item to direct steam contact at the required temperature and pressure for the specified time. Thus, there are four parameters of steam sterilization: steam, pressure, temperature, and time.

What is importance of sterilization?

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.

Which is the best method of sterilization?

Boiling water at a high temperature (100 degrees C) is capable of destroying almost all forms of bacteria and viruses. The time duration should be at least 20 minutes.

What are the methods of sterilisation?

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.

Which is the best method of sterilization?

Of all the methods available for sterilization, moist heat in the form of saturated steam under pressure is the most widely used and the most dependable.

How many types of sterilization methods are there?

With that said, there are three main types of sterilization methods common within the scientific community today. They are steam, dry heat, and ethylene oxide (EtO) sterilization.

What are the processes of sterilization?

Three main sterilization processes for packaging material are in common use, either individually or in combination: irradiation, heat, and chemical treatments. Irradiation involves ionizing radiation using gamma rays from cobalt-60 or cesium-137.

What is importance of sterilization?

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 chemical is used for sterilization?

Common chemical sterilants used in healthcare1 include: Ethylene oxide (EtO) Hydrogen peroxide gas plasma (HPGP) Vaporized hydrogen peroxide.

What are the physical methods of sterilization?

Physical methods of sterilization- Heat, Filtration, Radiation
  • Red Heat.
  • Flaming.
  • Incineration.

Who is the father of sterilization?

Joseph Lister, the Man who Sterilized Surgery.

What is the conclusion of sterilization?

When properly used, disinfection and sterilization can ensure the safe use of invasive and non-invasive medical devices. However, current disinfection and sterilization guidelines must be strictly followed.
