Parts and components for cleaning should rest directly on the tank floor, as they could damage the tank or scratch the parts and components through vibrations caused by the ultrasound.

And the cavitation fields, which are the areas in which the ultrasonic cleaning action takes effect, are not positioned at the bottom of the tank, but a few centimetres above. This is why Elma offers matching immersion and insert baskets made from either plastic or stainless steel for the various Elmasonic devices.
