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 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 is sterilization and its methods?

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.

What is the main type of sterilization?

Although there are numerous physical and chemical processes used for proper sterilization of equipment, there are just a few main ones. 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 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 an example of sterilization?

Ethylene oxide gas has been used since the 1950s for heat- and moisture-sensitive medical devices. Within the past 15 years, a number of new, low-temperature sterilization systems (e.g., hydrogen peroxide gas plasma, peracetic acid immersion, ozone) have been developed and are being used to sterilize medical devices.

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 sterilization means?

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 the principle of sterilization?

Sterilization can be done by physical or chemical methods. Steam under pressure, dry heat, ethylene oxide (EtO) gas, gas plasma, and liquid chemicals like glutaraldehyde are the principal sterilizing agents used in healthcare.

What are the uses of sterilization?

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.

What are physical methods of sterilization?

Physical methods of sterilization- Heat, Filtration, Radiation.
