Founded in 1998, TSO3 originally developed a unique sterilization process based on only ozone as the sterilizing agent. It offered major savings over competing low-temperature sterilization methods, greater safety for both users and patients, and was considered a “green” technology.

The original 125L Ozone Sterilizer received regulatory clearances from both Health Canada and the United States Food and Drug Administration. The 125L Ozone Sterilizer also received additional clearances, expanding the field of application to a wider range of complex surgical instruments and attesting to the high sterilization efficacy of the TSO3 STERIZONE® sterilization platform.

In 2009, the Company developed a a new generation sterilizer, the STERIZONE® 125L+ Sterilizer utilizing hydrogen peroxide and ozone, as sterilizing agents. The new sterilizer was also equipped with a newly developed Dynamic Sterilant Delivery System™. This product provided both improved cycle time and material compatibility enabling increased throughput of a wider range of medical devices, including some of the most complex and delicate instruments used in Minimally Invasive Surgeries (MIS). The STERIZONE® 125L+ Sterilizer was licensed by Health Canada in 2009 and CE marked in 2010.

In December 2014, the Company achieved another major milestone in its history, when it received 510(k) clearance from the FDA of the United States. This clearance allowed the Company to initiate commercial activities for the STERIZONE® VP4 Sterilizer in the United States. The STERIZONE® VP4 and 125L+ Sterilizers use similar technology platforms. The STERIZONE® VP4 Sterilizer however features a single cycle that can simultaneously sterilize flexible, rigid, and general medical devices in the same load. The FDA recognized the uniqueness of this sterilizer by issuing a brand new Product Code (“PJJ”), representing sterilization technologies using two or more sterilants. The STERIZONE® VP4 Sterilizer is the only product in this Product Classification.
