ETO Sterilizer

ETO sterilizer is known as Ethylene Oxide sterilizer which is mainly used to sterilize medical and pharmaceutical products that cannot support conventional high temperature steam sterilization.

Eto sterilizer

ETO Sterilizer is highly effective sterilizing equipment and perfect for heat sensitive tools and devices as it uses only ethylene oxide gas for sterilizing the substances. Our provided ETO Sterilization guarantees that a safe and sterile product will be delivered to the market every time. The product offered by us satisfies the need of the clinic, hospitals, laboratories and medical device manufacturers who require a sterilizing facility for heat-sensitive items which would otherwise be smashed by high temperature, pressures, or vacuums.

Extremely low electrical consumption


Brief Description of ETO Sterilizer

Define: Sterilization with ETO is a low-temperature process that uses Ethylene Oxide gas to reduce the level of infectious agents. ETO is used in gas form and is usually mixed with other substances, such as CO2 or steam. It is known as ETO Sterilizer. Ethylene oxide sterilization is a chemical process consisting of four primary variables such as gas concentration, humidity, temperature and time. Further the offered; Ethylene oxide is an agent that disrupts the DNA of microorganism, which prevents them from reproducing. These ETO sterilizations that are known for the safe and sterile product which will be delivered to the market each and every time.

Why ETO stetilization?

ETO Sterilization is recognized technology with excellent history and high reliability with Environment considerations. We are taking the utmost care while manufacturing the ETO Sterilization which is made with strict emissions requirements. Further no depleted radio logical waste to contend with the effect of radiation on product or packaging materials is sometimes prohibitive effect of radiation on drugs may be problematic.

Features of ETO Sterilizer

To Sterilize Surgical Medical Device products like I.V. Sets, Disposable Syringes, Disposable Surgical Set, catheter, Urine Bag, reduce microbiological load and increase life span of material.Modular construction of chamber.
It is very easy to operate.
Fully automatic operation based on PLC control (optional).

Better productivity and lesser mixing time.

Overview of ETO Process

Normally the ETO sterilization process consists of three basic steps:


Steps taken for ETO Sterilization Process

Evacuation: Evacuation means the phase to remove the air that is present in sterilization chamber.
Nitrogen dilution: The phase where the nitrogen is introduced into the chamber. It is injected and then immediately removed. And even aids in the removal of any air that is in the chamber.
Humidity Injection and Humidity dwell: In this phase of process the Humidity is injected into the chamber and it is held at a certain pressure for a certain amount of time. This replenishes the moisture present in the load which was lost during its removal from the preconditioning room and transfer to the chamber, and during the evacuation and nitrogen dilution phases. Further the moisture in the chamber also allows easier absorption and desorption of the EO gas in and out of the products.
Sterilant Injection and EO dwell: The EO Sterilant is injected into the chamber and is held in a dwell phase for a period of time in order to achieve the validated sterility assurance level.
Sterilant Removal: In these phase of Sterile Removal, the vacuum is pulled deeper to remove all of the ethylene oxide from the chamber and the product.
Nitrogen Wash: Nitrogen Wash purpose is to essentially wash off any ethylene oxide that is remaining in the chamber.

Air break: At the last phase the vacuum is released and brings the sterilization chamber back to atmospheric pressure before the doors can be opened.

Sterilization Technologies

Sterile offers safe and consistent sterilization services with several cutting-edge technologies. We rely on processes such as Ethylene Oxide (EO) sterilization or ETO sterilization, gamma sterilization, and electron beam (E-beam) sterilization. Each method is best matched for diverse applications and our knowledgeable sales representatives can help you choose the best process for your requirements.

Sterilization Facility Design

The process of E.O. gas sterilize:

1.Put the goods in the sterilizer (Lock the door, make sure it can’t be open by anyone else).
2. Temperature Adjusting: Adjust the temperature to the necessary 50ºC, takes about 1~2 hours.
3. Pre-Vacuum: Vacuum the air in the sterilizer, it takes about 6~30 minutes.
4. Air Pressure Holding Test: Checking the tightness of sterilizer, make sure no gas leaks.
5. Pre-humidification: pre-humidify the sterilized goods to 55%RH humidity, it takes 1-1.5 hours.
6. Inject EO gas into the chamber: 20- 30 minutes
7. E.O. Sterilizing: make sure every condition is not changed, keep it 4 – 8 hours.
8. Sterilization finishes: clear the residue E.O. gas. Vacuum degree 60 Kpa. Blow Air inside, repeat at least 3 times. It takes about 1 hour.
9. Unlock and open the door, pull the cart outside the sterilizer.

Our eto sterilizer chamber can sterilize two batch of cargos in 24 hours.

The Process of Ethylene Oxide Sterilization:
