ETO Sterilizer Description
Ethylene Oxide (EO or ETO) Gas is commonly used to sterilize objects sensitive to temperatures greater than 60°C and /or radiation such as plastics, optics and electrics. Ethylene oxide treatment is generally carried out between 30°C and 60°C with relative humidity above 30% and a gas concentration between 200 and 800 mg/l, and typically lasts for at least three hours. Ethylene oxide penetrates well, moving through paper, cloth, and some plastic films and is highly effective. ETO can kill all known viruses, bacteria and fungi, including bacterial spores and is compatible with most materials (e.g. of medical devices), even when repeatedly applied. However, it is highly flammable, toxic and carcinogenic.
Ethylene oxide sterilization is a chemical process consisting of four primary variables: gas concentration, humidity, temperature and time. Ethylene oxide is an agent that disrupts the DNA of microorganisms, which prevents them from reproducing. EO sterilization assures that a safe and sterile product will be delivered to the market each and every time.
Salient Features of ETO Sterilizer
Process Operation of ETO Sterilizer
Ethylene Oxide Sterilization (Sterilisation) offers various distinct advantages over the conventional steam sterilizers (sterilisers), being a DRY & COLD (operates at 50ºC ) process proves very useful in sterilization of expensive items, also it has got a unique penetration ability, so it is very useful in sterilization (Sterilisation) of expensive and delicate items such as Cardiac catheters, Stents, IOL’s Tubings, various types of scopes, sharp surgical instruments etc., its unique mode of action, also enhances the life of several surgical accessories & disposables items thus making them perfectly reusable.
Types of EO Gas Sterilizers
We are one of the leading EO Gas Sterilizer manufacturer in India. We manufacture below two types of ETO sterilizers:
Semi Automatic Operation Mode EO Sterilizer: In this type of control mode there are analog type buttons onto control panel of the machine through which machine operation procedure will be done.
Fully Automatic Operation Mode EO Sterilizer: This is PLC HMI based fully automatic control mode equipment in which there is HMI mounted onto control panel of the machine through which operation procedure done.

FAQ of ETO Sterilizer
What products can be sterilized using an ETO Sterilizer?
ETO Sterilizers are ideal for surgical and medical devices including I.V. Sets, disposable syringes, catheters, urine bags, cardiac catheters, stents, IOLs, tubings, scopes, and sharp surgical instruments. They are also useful for spices, dried nuts, packed cereals, and other items requiring low-temperature sterilization to reduce microbiological load while increasing material lifespan.
What are the key features and advantages of Adinath’s ETO Sterilizer?
Key features include modular chamber construction, availability in sizes from 0.5 to 40 cubic meters, fully automatic PLC/HMI or semi-automatic operation, SS 304/316 contact parts, in-built aeration, and both warm & cold cycle options. Advantages include low-temperature (around 50°C) dry sterilization, excellent penetration, compatibility with most materials, and reusability of expensive/delicate items compared to steam sterilizers.
What are the available models and technical specifications?
Adinath offers models such as AETOS-2.6 (70 liters), AETOS-4.5 (125 liters), and AETOS-8 (200 liters), with larger capacities up to 40 cubic meters available. They use ETO gas cartridges (40g to 170g), require compressed air, and operate on 220V single phase. Custom power voltage adjustments are possible.
Is ETO Sterilization safe and what precautions are needed?
ETO is highly effective but flammable, toxic, and carcinogenic, so proper handling, aeration (to remove residual gas), and safety protocols are essential. Adinath’s systems include built-in aeration and can provide IQ/OQ/DQ documentation. The process ensures safe, sterile products when operated correctly by trained personnel.
