Washer disinfectors play a critical role in medical and pharmaceutical applications by preparing instruments for sterilization or providing disinfection for subsequent use. These systems effectively remove residues such as blood, proteins, and other contaminants from surgical instruments and equipment through automated washing and thermal disinfection cycles.

Proper cleaning is essential for successful steam sterilization. Without thorough cleaning and removal of debris, sterilization cannot be guaranteed. A clean surface allows steam to penetrate and contact all instrument surfaces effectively during the sterilization process.

Research has demonstrated that bacteria can survive steam sterilization cycles when protected by dried debris or organic material. This highlights the crucial role of washer disinfectors in ensuring complete decontamination before sterilization.

After completing the washer/disinfection cycle, instruments can be visually inspected, packaged in appropriate sterilization pouches or wraps, and properly sealed before processing in the sterilizer.
