Cleaning Surgical Instruments — Testing Your Ultrasonic Cleaner Machine

To determine if your ultrasonic cleaner is working properly, simply put water and properly mixed ultrasonic solution in the tank. Turn on machine and view the surface of the water. If you see "sonic" waves your machine is working. If the surface of the water is totally flat, your machine may have a problem with the transducer(s).

The second test is called the foil test. Simply place a small piece of aluminum foil in the bottom of a filled tank and run for 5-8 minutes. Remove foil and it should be pelted with small holes and dents. This verifies that the ultrasonic machine is working properly.
