The Renal Systems Group carries two types of cold sterilants. Renalin® 100 is used for reprocessing dialyzers with the Renatron® II 100 Series machine. Actril® is used for surface disinfection. Both products are a mixture of peracetic acid, hydrogen peroxide and acetic acid. They leave no toxic residues and after reacting with organic material, they decompose into oxygen and acetic acid. These cold sterilants destroy viruses, bacteria, spores and fungi.
