What chemicals are used in my sterilizer or high-level disinfectant equipment?
Do you know the chemicals used in low-temperature sterilizers or high-level disinfectant equipment that you use every day? Here is a quick, high-level guide with some of the most common brands and chemicals used in them.
Low-Temperature Sterilizer Brands, Chemicals and Concentrations
|Company||Low-Temp Sterilizer||Chemical Biocide||Source Concentration (w/w)|
|Johnson & Johnson (ASP)||Sterrad||Hydrogen Peroxide||58 – 95%|
|Steris||Amsco Eagle 3017||Ethylene Oxide||100%|
|3M||Steri-vac 5XL. 8XL||Ethylene Oxide||100%|
|3M||Steri-vac GS Series||Ethylene Oxide||100%|
|TSO3/Getinge||STERIZONE||Hydrogen Peroxide, Ozone||50% H2O2, O3 generated internally|
Something very important to note – many people believe the myth that the hydrogen peroxide used in low-temperature sterilizers is the same as the hydrogen peroxide you can get at the grocery store. Unfortunately, this is not true. The concentration in the sterilizers can go as high as 95% – much higher and more dangerous than the hydrogen peroxide from the grocery store (~3%).
High-Level Disinfection Equipment Brands and Chemicals
|Company||High-Level Disinfection||Chemical Biocide|
|Steris||System 1e||Peracetic Acid|
|Medivator||Medivator||Peracetic Acid, Ortho-phthalaldehyde (OPA)|
|Olympus||OER- PRO||Gluteraldehyde, Peracetic Acid|
|Custom Ultrasonics||System 83||Gluteraldehyde, Peracetic Acid, OPA|
|Johnson & Johnson (ASP)||ENDOCLENS-NSX||OPA|
Worker Exposure Limits For the Chemicals

With advances in sterilization technology, and shorter cycle times, technicians are now processing instruments multiple times per day, using more concentrated chemicals than previously, putting them at increased risk of exposure to hazardous levels of sterilant vapor. Every day, more and more hospitals are choosing to monitor the air around this potentially dangerous equipment – shouldn’t you?
