ETO Sterilizer

What is ETO sterilization? What is Ethylene Oxide Sterilization Process?

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. Almost all healthcare products which are sensitive to high temperature and moisture can sterilize by this process where steam sterilization process will not work.

So, what is the Ethylene oxide sterilization process?

There are four primary variables used in this process. These are temperature, humidity, the time and gas concentration. In this process, a product which needs to be sterilized kept in a vacuum container. Then the product is exposed to ethylene oxide gas. Ethylene oxide gas is an alkylating agent that can disrupt the DNA of bacteria, micro-organisms thus stop them to reproduce in the product. Thus the Ethylene oxide gas is used to sterilize the healthcare products and instruments.

There are several advantages of ETO Sterilizer like they operate at a very low temperature, enjoys high efficiency which has the power of destroying the microorganisms which include the extremely resistant spores, large sterilizing volume or chamber capacity, non-corrosive to metal, rubber materials and plastic.

SSQLLP is well known manufacturer, supplier of sterilizer in Ahmedabad, Gujarat, India.

The Ethylene sterilization process is conducted into three main phases which are the pre-conditioning phase, the sterilization phase, and the Aeration phase.

1. Pre-conditioning phase:

This phase allows microorganisms to grow under controlled temperature and humidity. In this phase, the controlled temperature and humidity is provided such that the passive infectious agents, micro-organisms, and bacteria come into the active state.

2. Sterilization phase:

This is the major phase in which the product is exposed to a sterilizing agent say ethylene oxide under a controlled temperature, pressure and humidity. The process can be used to sterilize multiple devices simultaneously.

3. Aeration phase:

In this phase, Ethylene oxide gas is removed. The batch loads under a controlled temperature and humidity to eliminate the residue of ethylene oxide gas.
