A novel sterilization process compliant with the most demanding medical regulations

Mode of action

Understand what's going on during the sterilization process

Devices to be sterilized are placed in the SteriBox and a few drops of water are added on a blotting paper. The SteriBox is closed and slid inside the SteriBase. Ozone, the biocide gas, is generated from air in situ by 172 nm V-UV radiations and effectively diffused inside the container.

High gas concentration and humidity are maintained. Parameters are monitored to guarantee process efficiency and effective destruction of all microorganisms (bacteria, yeast, fungi, viruses and spores).

All remaining biocide gas is actively removed and turned back to oxygen by 254 nm UV radiations. The content of the SteriBox is sterile and ready for use.

Microbial effectiveness

The SterOx System is compliant with norms relative to the microbial effectiveness of the sterilization process:

  • ISO 14937:2009 Sterilization of healthcare products – General requirements for characterization of a sterilizing agent and the development, validation and routine control of a sterilization process for medical devices
  • ISO 11138-7:2019 Sterilization of health care products — Biological indicators — Part 7: Guidance for the selection, use and interpretation of results

An overkill approach was used on the most resistant microorganism, based upon an initial concentration of at least 10e6 CFU (colony-forming units) of the recommended test organisms. The dynamics of Geobacillus stearothermophilus inactivation follows first order kinetics against the dose with an R2 value (coefficient of determination) of more than 0.8.

Geobacillus stearothermophilus was chosen to be the reference microorganism and biological indicator for the sterilization process as it represents the greatest challenge, and as it demonstrates a linear lethality relation to the critical process parameter “dose” (ozone concentration by the time).

  • This field is for validation purposes and should be left unchanged.


  • SteriLux technology drastically changed my surgeon and endoscopist days. I can now have the assurance of working with sterile equipment. I’ve dreamt of a solution without chemicals my whole life as a vet!

    Dr. Adam Switzerland

  • SteriLux device has quickly found its place in our sterilization arsenal. The machine is efficient and easy to use. It is the ideal complement to our autoclaves to sterilize all our heat sensitive devices. We have been looking for a solution to this problem for a long time and are delighted to be equipped. The low cost of consumables makes the cycles economical and we do not hesitate to use it daily. The absence of toxic effluents with this technology is a real asset.

    Dr. Guillaumot France

  • I am very attentive to the safety of my employees and my patients, SterOx System is, without doubt, the best solution combining safety and efficiency for cold sterilization.

    Dr. Libermann France

  • The device proposed by SteriLux finally offers an effective and safe low temperature sterilization alternative to our veterinary clinics, what a relief!

    Group director France

  • The after-sales service is very present and responsive. I highly recommend SterOx Sytem!

    Dr. Proment Luxembourg

  • This chemical-free cold sterilization solution has changed the lives of our staff! Being able to reprocess all our heat-labile instruments using a controlled sterilization process is a real added value for our clinic.

    Dr. Bozon France

  • We use the SterOx System to sterilize all our instruments, including but not limited to our respiratory endoscopy equipment and our electric scalpel parts. The handling of the device is quite simple and very standardized.

    Dr. Moulin Belgium

  • A safe and efficient solution for low temperature sterilization!
