ROSS M1 Advantage


Portable sterilization of surgical instruments in remote, low resource settings using sterilant generated on-site and decomposed into non-toxic compounds.

The Rugged Ozone Sterilization System

ROSS M1 Advantage

The ROSS M1 utilizes a sterilant that is catalytically decomposed into to oxygen and water vapor at the end of the sterilization cycle.

There are many advantages associated with the ROSS M1 process as it does not produce toxic by-products or require high temperatures to inactivate contaminant microorganisms.

  • No toxic chemical handling
  • No toxic sterilization by-products
  • No requirement for clean water source
  • Stand-alone device, no infrastructure required
  • Rechargeable battery
  • Dust- and water-proof enclosure
  • Fast process time of approximately 35 minutes
  • Demonstrated safety: biocompatibility
  • Demonstrated efficacy: inactivates most-resistant organism




Current field sterilizer used by the Special Operations Forces is too cumbersome and unreliable with a large logistics footprint requiring potable water and a power source.
