Sterilization Methods

The Sterilization Methods series considers the diffent methods of sterilization used in the medical, dental, laboratory and pharmaceutical fields.

Sterilization Methods

This post is the kick off of a long discussion concerning the evolution of the different methods of sterilization that were developed over the years.

Sterilization by Heat

In this post we continue our discussion about the different sterilization methods available.


In order to understand why autoclaves are most commonly used for sterilization we need to understand its driving force - steam.

The Right Steam Does The Right Thing

What happens to steam when conditions along the way from the steam source to the chamber are not ideal and how these conditions can hamper the sterilization process yielding a less than desirable result?

EtO - Ethylene Oxide Sterilization

In this post we explore low temperature sterilization methods for heat sensitive and moisture sensitive loads.

Formaldehyde: More than Meets the Eye

Another low temperature method for sterilizing heat sensitive items is Formaldehyde sterilization. Here we discuss it.

Sterilization by Gamma Irradiation

Despite its negative connotation, radiation’s benefits and contemporary applications are many, such as in medicine, communication, and science.

How Does Filtration of Liquids in the Lab Work?

Filtration is an interesting sterilization method in laboratories. It’s the only method that uses force to separate rather than to kill.

Air Filtration in Autoclaves

In this post you’ll learn about air filtration, used as a way to protect the lab environment and lab staff from contamination.

Methods of Low-Temperature Sterilization: Ozone

Ozone can be used to sterilize heat and moisture-sensitive medical devices. Ozone, also known as trioxygen, is an inorganic molecule with the chemical formula O3.

Low Temperature Hydrogen Peroxide Plasma Sterilization

The last method of low temperature sterilization for us to explore is the method of hydrogen peroxide plasma sterilization.

Sterilization Methods Summary

We explored the different ways to kill or remove deadly bacteria, viruses, and harmful pathogens.
