We have reached the end of the Sterilization Methods Series where we explored the different ways to kill or remove deadly bacteria, viruses, and harmful pathogens.

How do you select the appropriate sterilization method when there are so many choices available? Your decision will depend on many different parameters, including:

The material that needs to be sterilized. Is the material heat sensitive? Is it sensitive to moisture, gas or radiation?
The nature of the microorganisms that need to be destroyed or removed.
Additional considerations are: time, safety and budget.

The sterilization methods series can help you make an informed decision. It includes 12 blog posts and covers 9 different sterilization methods that can be divided into two major categories: heat and non-heat sterilization methods.

The last category is physical sterilization methods:
