Revital-Ox Resert XL HLD is an oxidative chemistry, not an aldehyde. Its patented formula contains the active ingredient Accelerated Hydrogen Peroxide (AHP) at a reduced level of 2%. At this level, Revital-Ox Resert requires no special ventilation under normal use conditions, and has no irritating odor. Revital-Ox is made with biodegradable ingredients and requires no special detoxification or deactivation processes. Because it requires no heating and just one rinse, it can save on water and energy costs. You could save as much as 13 gallons of water per cycle depending on your AER and the previous chemistry used. Used in hospitals and endoscopy centers in the U.S. and abroad since 2009, Revital-Ox Resert has an excellent track record of use in reprocessing of endoscopes and surgical instrumentation.
