  • Page 9: Principles Of Operation

    4. Principles of Operation The ultrasonic electronic generator transforms AC line power to a 20 KHz signal that drives a piezoelectric converter/transducer. This electrical signal is converted by the transducer to a mechanical vibration due to the characteristics of the internal piezoelectric crystals. The vibration is amplified and transmitted down the length of the horn/probe where the tip longitudinally expands and contracts.
  • Page 10 as the load increases but the amplitude remains the same. The AMPLITUDE control allows the ultrasonic vibrations at the probe tip to be set to any desired level. Although the degree of cavitation/ultrasonic energy required to process the sample can readily be determined by visual observation, the amount of power required cannot be predetermined.

    6. Preparation for Use INSPECTION Prior to installing the ultrasonic processor, perform a visual inspection to detect any evidence of damage, which might have occurred during shipment. Before disposing of any packaging material, check it carefully for small items. The ultrasonic processor was carefully packed and thoroughly inspected before leaving our factory.

    7. Operating Instructions (Getting Started) CAUTION Do not operate the power supply unless it is connected to the converter. • Never allow liquid to spill into the converter. • Do not allow a Microtip to vibrate in air. • Do not allow the vibrating Microtip to contact anything but the sample. •...
  • Page 16 secure the clamp to the upper section of the convertor housing only. Never secure the clamp to any other portion of the convertor/probe assembly. If you are using an acoustic enclosure mount the convertor properly in the convertor collar. 9. Connect the converter cable to the power supply and then to the top of the convertor.

  • Page 24 For example, the ½” horn should be immersed ¾” below the liquid surface. Immersion depth can be less for larger horns and may have to be more for smaller probes used at higher intensity. Foaming and Aerosoling Aerosoling and foaming generally occur when the tip is not immersed far enough into the solution.

  • Page 26: Maintenance

    9. Maintenance It is recommended to periodically inspect the unit, both visually and physically, to insure optimum and safe performance. This inspection should be scheduled as a routine maintenance procedure, done with the unit power OFF and with the unit unplugged from the AC power source. Long exposure to acids or caustics results in corrosion of metal parts or components.
  • Page 27 Follow the steps below for attaching and detaching accessories: Disconnect probe from convertor. Use the wrench set provided with the system. Clean threaded stud. Use alcohol and a cotton swab to remove any debris on the threading of the connecting stud. Allow the alcohol to dry completely. 3.

  • Page 29: Troubleshooting

    10. Troubleshooting Your Ultrasonic Processor was designed to provide you with years of safe and dependable service. Nevertheless, because of component failure or improper usage, the possibility does exist that it might not perform as it should, shut down or stop working all together. The most probable causes for malfunction are listed below and should be investigated.

  • Page 30: Service / Return Of Equipment

    11. Return of Equipment It is suggested that an Ultrasonic Processor in need of repair be sent back to the factory. In order to receive prompt service; always contact your Customer Service Representative before returning any instrument. Include date of purchase, model number and serial number. Please obtain a Return Authorization Number prior to returning the instrument.

  • Page 32: Addendum

    Addendum Converter Cooling Continuous sonication will cause both the probe and sample temperature to increase. The heat will transfer up to the converter. If the converter overheats the internal crystals can crack and the entire converter will require replacement. Converter damage due to overheating is not covered under warranty.
  • Page 33 Frequently Asked Questions (FAQ) Probe size vs. Sample volume Selecting the proper size probe is a critical factor when sonicating a sample. The sample volume to be processed must correlate with the tip diameter. Each probe has a recommended sample volume range. This range may overlap with other probes.
  • Page 34 to be mixed effectively. Without effective mixing you cannot ensure the entire sample volume will pass below the tip and become processed. The probe should be immersed at least 1.5 times the tip diameter. Before processing actual samples, it is recommended to test the probe in a vessel filled with water to observe the ultrasonic energy and the flow pattern of the liquid.
