Endoscope washers (washer-disinfectors) are automated medical devices that clean and disinfect flexible endoscopes after procedures. Hospitals use them for high-level disinfection, removing bioburden, mucus, and microbes from channels using enzymatic detergents, high-flow water jets, and peracetic acid/hydrogen peroxide. Models like Uniclean PLE 3 process 1-4 scopes simultaneously with leak testing, rinsing, and drying cycles. Essential for endoscopy suites, they prevent infections, ensure patient safety, and comply with SGNA/APIC guidelines—far superior to manual cleaning.
