What is Sterilization?
- Sterilization is a phrase referring to any
process that eliminates or kills all forms of
microbial life, including transmissible agents(
such as fungi, bacteria, viruses, spore forms,
etc.) present on a surface, contained in a fluid,
in medication, or in a compound such as
biological culture media. - Sterilization can be achieved by applying the
proper combination of heat, chemicals, and
irradiation, high reassure, filtration.
4
Types of Sterilization Methods
- There are mainly following sterilization methods
are in use. - Heat based Sterilization
- Chemical based Sterilization
- Radiation Sterilization
5
Let us talk about the ETO Sterilization
- ETO Stands for Ethylene Oxide Sterilization
- Eto Sterilizer is used to sterilize hospital
instruments - Ethylene Oxide sterilization process ensures that
a safe product is delivered each time. - The time taken by the process varies as per the
product which needs to be sterilized. - Usually, the time taken lies between 36 to 48
hours while the exposed gas time is just 1 to 6
hours varies as per the product to be sanitized.

Why where ETO sterilization used?
- ETO Sterilization process is widely used for the
sterilization of healthcare devices and
instruments. - World / industries have been praising
sterilization by steam superlative for
destroying bacteria, fungi and spores. - Steam sterilization is also most cost effective
easy to use method available but steam is not
applicable to all materials and instruments.
8
Proces of the Ethylene oxide sterilization
- There are four primary variable used in this
process. - These are temperature, humidity, the time and the
gas concentration. - In this process, a product which needs to be
sterilized kept in vacuum container. - Then the product is exposed to Ethylene oxide
gas. - Thus the Ethylene oxide gas is used to sterilize
the healthcare products and instruments.
9
Advantage of Eto Sterilizer
- ETO Sterilizer operate at a very low temperature
- High efficiency- destroys micro- organisms
including resistant spores. - Large sterilizing volume/ chamber capacity.
- Non-corrosive to plastic, metal and rubber
materials.
10
Disadvantage of Eto Sterilizer
- Excessively long cycle.
- ETO is flammable
- Requires special room conditions, safety
equipments and separate ventilation system. - Not recommended for flexible scope.
11
Sterilization Cycle in ETO Sterilizer
- There are 3 phase in ETO Sterilizer
- Pre-conditioning Phase
- Sterilization Phase
- Aeration Phase
