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.
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.
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.
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.
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.
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.
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.
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.
9. What Are Phenol Disinfectants? - Definition, Advantages & Disadvantages
Phenol is a disinfectant which kills bacteria by disrupting their enzyme systems. Understand the full definition and discover the details of this mechanism, and the advantages or disadvantages presented when using phenol.
10. Chlorine and Quaternary Ammonium Compounds: Advantages and Disadvantages
Chlorine and quaternary ammonium compounds are chemical disinfectants. Discover the advantages and disadvantages of using these disinfectants to kill bacteria in this lesson.
11. What Are Peroxide Antiseptics? - Definition, Types & Uses
Peroxides are chemicals containing two oxygen atoms with a covalent bond, used to clean living tissue or irradiate microbes. Learn about the full definition and examine types of peroxide antiseptics like hydrogen peroxide and peracetic acid, and discover their uses to kill microbes effectively.
12. What Is Ethylene Oxide? - Uses, Safety & Technology
Ethylene oxide can be quite helpful or harmful, depending on how educated you are on the subject of this powerful gas. Read on to uncover its uses, benefits, and dangers as well as its connection to technology.
13. Chlorhexidine, Iodine & Silver: Uses and Modes of Action
Chemical antiseptics used for treating wounds kill harmful microbes in different ways. Learn the definition of antiseptics, and examine the uses and modes of action of four different antiseptics: iodine, iodophors, silver compounds, and chlorhexidine.
14. Particle Accelerators: History, Types & Uses
This lesson will introduce the history of particle accelerators, how they are used, as well as providing an overview of the types of particle accelerators in use today. A short quiz will follow.
15. Antisepsis: Definition & History
Antisepsis is a critical part of the surgical preparation and recovery processes. In this lesson, you'll learn about the history of antisepsis practices, including those still used in medicine today.
16. Ethylene: Properties & Uses
Ethylene is a colorless and flammable hydrocarbon that is useful in commercial and biological applications. Learn about the structure, properties, and commercial/biological uses of ethylene.
17. Joseph Lister: Biography, Facts & Inventions
Joseph Lister (1827-1912) was a British surgeon who pioneered antiseptic surgical techniques, drastically reducing surgical mortality rates from nearly 50% to 15%. In this lesson, learn about his life, discoveries, and legacy.
18. Ammonium Hydroxide: Formula & Uses
Ammonium hydroxide is a colorless solution that is made up of ammonia and water. Learn about the formula of ammonium hydroxide, and explore its uses in cleaning, manufacturing, and the food industry.
19. What Is Bacteriostatic Water? - Definition & Uses
Water can contain bacteria, but rather than killing off bacteria, bacteriostatic water prevents it from reproducing. In this lesson, we'll discuss the definition, uses, and cautions of bacteriostatic water.
