A 6 CFT ETO Sterilizer refers to an Ethylene Oxide sterilization chamber with a capacity of 6 cubic feet (CFT), designed for gas-based sterilization of heat- and moisture-sensitive medical devices, such as syringes, catheters, endoscopes, and surgical instruments. ETO sterilization uses ethylene oxide gas—a colorless, flammable, and explosive agent—to penetrate packaging and kill microorganisms, achieving a Sterility Assurance Level (SAL) of 10⁻⁶. This makes it ideal for delicate items that can’t withstand steam or high-heat methods.
These units are commonly used in hospitals, clinics, laboratories, and medical device manufacturing facilities for small-to-medium loads. The “6 CFT” size is compact, suitable for tabletop or benchtop operation, and processes loads in cycles typically lasting 1–6 hours, followed by aeration to remove gas residues.

Key Features of a Typical 6 CFT ETO Sterilizer
-
Chamber Design: Rectangular, stainless steel construction for durability and corrosion resistance.
-
Door Type: Single door with hydraulic or pneumatic sealing for safety and ease of use.
-
Capacity: Approximately 6 cubic feet (about 170 liters), handling 10–20 kg of materials depending on load configuration.
-
Power Consumption: Low (typically 220V/50Hz, 1–2 kW).
-
Safety Standards: CE and ISO certified; includes pressure relief valves, gas leak detectors, and interlocks to prevent operation if seals fail. Operates at low pressure (below atmospheric) to minimize explosion risks.
-
Customization Options: Adjustable shelves, integrated humidifiers, and aeration systems for faster post-cycle degassing.
- Cycle Parameters:
-
Gas Concentration: 450–1,200 mg/L.
-
Temperature: 37–63°C.
-
Relative Humidity: 40–80%.
-
Exposure Time: 1–6 hours.
-
Total Cycle Time: 3–8 hours, including preconditioning and aeration.
-
Process Overview
-
Preconditioning: Items are humidified to activate microbial spores.
-
Sterilization Phase: ETO gas is introduced in a sealed chamber; the gas diffuses into materials.
-
Aeration: Hot air or vacuum removes residual ETO to prevent toxicity.
-
Validation: Biological indicators confirm efficacy.

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.
