Ch 20: Sterilization and Antiseptic Techniques: Tutoring Solution

About This Chapter

The Sterilization and Antiseptic Techniques chapter of this College Microbiology Tutoring Solution is a flexible and affordable path to learning about antiseptic techniques and sterilization. These simple and fun video lessons are each about five minutes long and they teach all of the antiseptic and sterilization strategies required in a typical college microbiology course.

How it works:

  • Begin your assignment or other microbiology work.
  • Identify the sterilization and antiseptic techniques concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our college microbiology tutoring solution will benefit any student who is trying to learn sterilization and antiseptic techniques and earn better grades. This resource can help students including those who:

  • Struggle with understanding various sterilization methods, a wide range of antiseptics and disinfectants or any other sterilization and antiseptic technique topic
  • Have limited time for studying
  • Want a cost effective way to supplement their biology learning
  • Prefer learning biology visually
  • Find themselves failing or close to failing their sterilization and antiseptic techniques unit
  • Cope with ADD or ADHD
  • Want to get ahead in microbiology
  • Don't have access to their biology teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about sterilization and antiseptic techniques simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live microbiology tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn sterilization and antiseptic techniques on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Antiseptics, Disinfectants & Sterilization

1. Antiseptics, Disinfectants & Sterilization

This lesson will discuss the differences between antisepsis, disinfection, and sterilization as well as some of the methods used for sterilization and antiseptic compounds you may have used yourself.

Autoclaves and Moist Heat Sterilization: Use With Surgical Tools

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

This lesson will discuss what an autoclave is, how it works, and what it's used for. We'll also discuss the disadvantages of an autoclave, bacterial endospores, and how sterilization is important in the context of nosocomial infections.

Sterilization by Irradiation: Method & Types

3. Sterilization by Irradiation: Method & Types

This lesson will talk about ionizing and non-ionizing radiation, what they're used for and what the different types are. For example, we'll touch base on gamma irradiation, electron irradiation, x-ray irradiation and U.V. radiation.

What Is Gas Plasma Sterilization? - Definition and Applications

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

This lesson discusses something known as plasma as well as hydrogen peroxide gas plasma, ions, electrons, and more. We'll talk about how gas plasma is used for sterilization and what it kills.

Sterilization by Filtration: Advantages & Disadvantages

5. Sterilization by Filtration: Advantages & Disadvantages

This lesson will cover how sterilization may be achieved through the process of filtration. We'll discuss how it works, what it is, its advantages and disadvantages, and much more.

6. What Is Pasteurization? - Definition & Common Uses

This lesson will discuss pasteurization, Louis Pasteur, and mastitis. We'll focus in on how pasteurization works, what it's used on, and why it's important to your health.

Understanding How Sterilization Is Quantified

7. Understanding How Sterilization Is Quantified

This lesson will describe what certain values, such as the D-value, F-value, Z-value, and thermal death time mean and how to calculate the D-value given certain specified criteria.

Using Alcohol as a Disinfectant and Antiseptic

8. Using Alcohol as a Disinfectant and Antiseptic

This lesson will discuss how alcohol can be used as a disinfectant and antiseptic but not a sterilant. We'll also talk about what it kills and doesn't kill and why ethyl alcohol and isopropyl alcohol are the two most commonly used alcohol-based disinfectants.

What Are Phenol Disinfectants? - Definition, Advantages & Disadvantages

9. What Are Phenol Disinfectants? - Definition, Advantages & Disadvantages

We will explore a disinfectant known as phenol. We'll cover what its mechanism of action is, what it can and cannot kill, its advantages and disadvantages and its involvement in enzyme systems.
