About TSO3

TSO3 has perfected an innovative sterilization process using ozone as the sterilizing agent. The first product based on this technological platform is the 125L Ozone Sterilizer, which is intended for hospital sterilization units. The 125L – named after its 125-litre/4.3-cubic-foot capacity – was designed to sterilize heat and moisture-sensitive surgical and diagnostic devices which are expensive and in high demand from the surgical suite. The ozone sterilization process is a safe, efficacious, fast and cost-effective response to evolving sterilization needs.

The 125L Ozone Sterilizer by TSO3 was cleared for commercialization by Health Canada and by the U.S. Food and Drug Administration (FDA). TSO3 expects its first sales in 2005.

Founded in 1998, TSO3 currently has 51 employees, 15 of whom work in the sales and marketing team to support SKYTRON, the company’s exclusive distributor for North America. With over 30 years experience servicing operating room and decontamination-sterilization departments throughout North America, SKYTRON provides 120 sales representatives, 100 service representatives and sales support facilities with manufacturing suppliers in the United States, Canada, Finland, Japan and the Netherlands to support the sales activities of TSO3.
