Selected ETO sterilizer configurations manufactured by Aniruddh Healthcare.
Aniruddh Healthcare offers ETO sterilizer configurations for low-temperature Ethylene Oxide sterilization applications. ETO, also written as EO or EtO, is used when compatible medical devices or materials are sensitive to heat or moisture and require a low-temperature sterilization process.
An ETO sterilizer is a controlled chamber system used for Ethylene Oxide gas sterilization. The sterilization cycle is managed through process parameters such as temperature, humidity, gas concentration, exposure time and aeration.
EO gas can be considered for compatible heat- and moisture-sensitive medical devices and products that cannot be processed by conventional high-temperature steam sterilization. The appropriate method depends on the device, materials, packaging and validated process.
A typical EO gas sterilization cycle is built around controlled conditioning, gas exposure, evacuation or purge and aeration. The exact sequence and setpoints depend on the sterilizer, load and validated cycle.
The load is prepared under controlled environmental conditions appropriate to the validated process.
Humidity is controlled because moisture is an important process parameter for ETO sterilization.
Ethylene Oxide is introduced into the chamber according to the selected and validated cycle.
The load remains exposed to the required process conditions for the validated exposure period.
The chamber is evacuated and purged according to the sterilizer cycle and safety configuration.
Post-sterilization aeration is required to reduce residual ETO before compatible products are released for use.
ETO (Ethylene Oxide) sterilization is a low-temperature process used for medical devices and materials that may be damaged by heat or moisture. The process is controlled through validated parameters such as gas concentration, temperature, humidity, exposure time and aeration.
| Process | Ethylene Oxide (ETO) gas sterilization |
| Temperature | Model and validated cycle dependent |
| Humidity | Controlled according to validated process |
| Gas concentration | Validated cycle dependent |
| Exposure time | Validated cycle dependent |
| Control | Manual / Automatic options |
| Chamber | Stainless-steel construction, model dependent |
| Aeration | Integrated or separate configuration, as specified |
Final sterilization parameters must be established and validated for the specific load, packaging, sterilizer configuration and intended use. ETO loads require appropriate aeration before patient use.
Compact configuration for selected healthcare and laboratory requirements.
Medium-capacity configuration for higher sterilization loads.
Higher-capacity configuration for larger loads and facility requirements.
Large-capacity configuration for higher-volume sterilization requirements.
Large chamber configuration for facilities requiring higher sterilization capacity.
Customized chamber capacity can be manufactured according to the required load, application and sterilization requirements.
Manual configuration for applications where the operator requires direct control of the sterilization process parameters according to the validated cycle.
Automatic configuration with controlled process sequence and programmable operation according to the selected machine configuration and validated cycle.
A typical ETO process includes preconditioning and humidification, gas introduction, exposure, evacuation or purge and aeration. Because ETO is hazardous, installation and operation require appropriate ventilation, exhaust, monitoring, safety controls and validated aeration.
This page describes general equipment capabilities. Actual cycle parameters, safety systems and compliance documentation should be finalized for the specific machine and application.
An ETO Sterilizer is equipment used for Ethylene Oxide gas sterilization of compatible heat- and moisture-sensitive medical devices and products.
ETO, EO and EtO are commonly used abbreviations for Ethylene Oxide. The terms ETO sterilizer and EO gas sterilizer therefore refer to the same basic sterilization technology, subject to the specific equipment and process configuration.
Aniruddh Healthcare currently lists 50 L, 100 L, 150 L, 200 L and 250 L configurations, along with customized chamber capacities according to application requirements.
Yes. The page lists manual and automatic control configurations. The final control architecture depends on the selected machine configuration and validated sterilization cycle.
Yes. ETO loads require appropriate post-sterilization aeration to reduce residual Ethylene Oxide before release for patient use. The required aeration conditions depend on the load, materials, packaging and validated process.
Capacity should be selected from the actual load profile, packaging, product dimensions, required throughput and validated sterilization process. Share your load details with Aniruddh Healthcare for configuration discussion.
