Miele's new PG 8535 / 36 washer-disinfectors set standards in terms of reprocessing surgical instruments in hospitals and outpatient surgeries and glassware for industrial, environmental and research laboratories. This series offers many innovations such as the new freely programmable Profitronic+ controls, “Perfect Speed” spray arm sensing, “Perfect Flow” ultrasonic volume control technology and a “Perfect Pure” conductivity meter. The design of the smooth surfaces and controls behind glass prohibits soil and bacteria from collecting and simplifies wet-wipe disinfection after every use.
