Pasteurmatic washers are specifically designed to perform a mechanical wash combined with thermal pasteurization. This dual approach ensures that medical devices and instruments are thoroughly cleaned by physically removing organic and inorganic material through mechanical action, such as spray jets and agitation. Following the mechanical wash, the pasteurization process involves subjecting the items to high temperatures for a set period, effectively killing or reducing the number of microorganisms without compromising the integrity of the devices being cleaned.

This combination is crucial in healthcare settings where sterility and hygiene are paramount. It allows for a more effective cleaning process than either method alone, enhancing the overall efficacy of the washing and disinfection process. In contrast, options implying only a mechanical wash, only thermal disinfection, or hand washing with chemical disinfectants do not capture the full capabilities and benefits provided by Pasteurmatic washers.
