Antiseptics, Disinfectants & Sterilization

1. Antiseptics, Disinfectants & Sterilization

Antiseptics, disinfectants, and sterilization are ways to kill harmful pathogens in the home and destroy potentially deadly healthcare-acquired infections. Learn more about the cleaning products compare and contrast the ways they defend against infection and the different types of pathogens each kills.

Autoclaves and Moist Heat Sterilization: Use With Surgical Tools

2. Autoclaves and Moist Heat Sterilization: Use With Surgical Tools

An autoclave is a bit like a pressure cooker, but instead of being used to cook food, it uses steam under pressure to kill off microorganisms on objects or surfaces. Discover how autoclaves are used to kill stubborn endospores and prevent nosocomial infection, as well as some of the downsides to using an autoclave.

Sterilization by Irradiation: Method & Types

3. Sterilization by Irradiation: Method & Types

Sterilization by irradiation is using radiation as a tool to destroy microorganisms. Discover the different types and methods used to sterilize by radiation, such as ionizing radiation and non-ionizing radiation.

What Is Gas Plasma Sterilization? - Definition and Applications

4. What Is Gas Plasma Sterilization? - Definition and Applications

Plasma, the fourth state of matter, is a gas-like substance made of particles like positive ions, and electrons. Understand the definition of gas plasma sterilization and learn about its applications and the relationship of free radicals to bacteria and health.

Sterilization by Filtration: Advantages & Disadvantages

5. Sterilization by Filtration: Advantages & Disadvantages

The concept of sterilization by filtration is a process that separates out unwanted matter to provide a cleaner substance. Explore the steps of filtration and learn both the advantages and disadvantages to this method.

What Is Pasteurization? - Definition & Common Uses

6. What Is Pasteurization? - Definition & Common Uses

Pasteurization is the process of heating and then rapidly cooling liquids or foods to kill microbes that may cause disease or expedite spoilage. Learn about pasteurization, its uses, and raw milk.

Understanding How Sterilization Is Quantified

7. Understanding How Sterilization Is Quantified

In order to be safe for use, medical devices need to be rid of any pathogens, like bacteria, through a process called sterilization. The sterilizing process has individual components that determine what is required to kill off all the microbes on an object. Investigate the values that help scientists determine what it takes to achieve sterilization, including the D-value, F-value, and thermal death time.

Using Alcohol as a Disinfectant and Antiseptic

8. Using Alcohol as a Disinfectant and Antiseptic

The three main types of alcohol are ethyl alcohol, isopropyl alcohol, and methyl alcohol. In this lesson, learn about each type of alcohol and how they can be used as disinfectants or antiseptics.

What Are Phenol Disinfectants? - Definition, Advantages & Disadvantages
