STERRAD™ Systems use a combination of hydrogen peroxide (H2O2) and low-temperature gas plasma to produce microbicidal free radicals, which work to sterilize medical devices and instruments by disrupting essential cell components.1, 2 The gas plasma dissociates any unreacted H2O2 into oxygen and water, removing any residual H2O2 from the load being sterilized.2

STERRAD™ Systems offer:

Safety for the User

STERRAD™ Systems reduce exposure to harmful residues, with studies showing that H2O2 emissions at the user’s breathing zone level are up to 67 times lower for STERRAD™ Systems compared with those produced by competitor sterilizers.3

Safety for the Patient

The advanced low-temperature gas plasma technology delivers rapid and safe sterilization, helping to ensure that medical and surgical instruments are reprocessed in line with the relevant guidelines, thereby potentially mitigating the risk of healthcare-associated infections.2, 4, 5

Unlike other commonly used sterilization systems, which have been shown to leave toxic residues on medical devices,6, 7 STERRAD™ Systems ensure safety for the patient by removing residual H2O2 during the plasma phase.2

As a result, thanks to the plasma technology, sterilization with STERRAD™ Systems does not require aeration of the load before handling, minimising lengthy instrument turnover times and helping to reduce delays to operating schedules which compromise patient safety.3

Safety for the Environment

STERRAD™ Systems use gas plasma to eliminate potentially harmful emissions, reducing their environmental impact compared with other toxic sterilants, such as ethylene oxide and formaldehyde gas.2
