Hydrogen peroxide sterilizers are low-temperature sterilization systems that utilize vaporized hydrogen peroxide (VHP) to sterilize heat- and moisture-sensitive medical devices. This method works by introducing a concentrated hydrogen peroxide solution into a vacuum chamber, where it is vaporized. The VHP then reacts with and oxidizes microbial components, effectively destroying bacteria, viruses, fungi, and spores. Hydrogen peroxide sterilization is a gentle yet highly effective process, leaving behind non-toxic byproducts (water vapor and oxygen). It is widely used for sterilizing delicate instruments, scopes, and electronics that cannot withstand the high temperatures and moisture of steam autoclaves. These sterilizers are crucial for reprocessing a wide range of complex medical devices, ensuring patient safety by providing a reliable and residue-free sterilization option in modern healthcare facilities.
