peracetic acid sterilization
Also written as: PAA — Peracetic Acid
A low-temperature liquid chemical sterilization process using peracetic acid as the sterilant for heat-sensitive and moisture-compatible instruments.
Full Definition
Peracetic acid sterilization is a rapid, low-temperature sterilization method that operates at approximately 50-55°C using a 35% peracetic acid solution. The process typically takes 20-30 minutes and is particularly suitable for heat-sensitive surgical instruments, flexible endoscopes, and implantable devices that cannot withstand steam sterilization. The sterilant breaks down into harmless water, oxygen, and acetic acid, eliminating toxic residue concerns. However, the process requires specialized equipment, strict solution monitoring, and is limited to instruments that can tolerate moisture and the corrosive nature of peracetic acid.
Usage
Usage note: Commonly abbreviated as PAA sterilization. Not suitable for instruments with aluminum components.
