    The Wash Cycle The AW31 utilizes ultrasonic waves, emitted from the bottom surface of unit, to break up and free contaminants from glass pipettes as they soak in a detergent bath. A fluid jet stream is also applied to assist in freeing contaminants left on inner and outer pipette surfaces. To ensure an even and uniform wash, pipettes are rotated in a cage while the ultrasonic waves and fluid jet are applied.

In the event that voltage drops below 90V, machine performance may lag. Conversely, if voltage exceeds 110V, equipment damage may result.
