INSTALLING THE ULTRASONIC PROCESSOR

The Ultrasonic Processor should be installed in an area that is free from excessive dust,

dirt, explosive and corrosive fumes, and extremes of temperature and humidity.

SECTION II – OPERATION

PRINCIPLES OF ULTRASONIC DISRUPTION

The ultrasonic power supply converts 50/60 Hz line voltage to high frequency electrical

energy. This high frequency electrical energy is transmitted to the piezoelectric

transducer within the converter, where it is changed to mechanical vibrations. The

vibrations from the converter are intensified by the probe, creating pressure waves in the

liquid. This action forms millions of microscopic bubbles (cavities) which expand during

the negative pressure excursion, and implode violently during the positive excursion.

This phenomenon, referred to as cavitation, creates millions of shock waves in the liquid,

as well as elevated pressures and temperatures at the implosion sites. Although the

cavitational collapse last but a few microseconds, and the amount of energy released by

each individual bubble is minute, the cumulative effect causes extremely high levels of

energy to be released into the liquid. The larger the probe tip, the larger the volume that

can be processed but at a lesser intensity. For information regarding the processing

capability of each probe, consult the tables below.

NOTE

The Ultrasonic Processor is available with three probes. A 2mm (5/64”) microtip, a 3mm (1/8”)

microtip, and a 6mm (1/4”) microtip. All probes are fabricated from titanium and are autoclavable.

The standard 3mm microtip can process between 250 microliters and 10 milliliters.

The 2mm microtip is optional and can process between 100 microliters and 5 milliliters.

The 6mm microtip is optional and can process between 10 milliliters and 25 milliliters.
