Page 6: Principles Of Operation
4. PRINCIPLES OF OPERATION The OM500 ultrasonic power supply 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 piezo- electric crystals. - Page 7 The OM500 ultrasonic homogenizer was designed to deliver constant amplitude to your liquid sample, regardless of these changes in load (much like the vehicle’s cruise control described above). As a liquid is processed, the load on the probe will vary due to changes in the liquid sample (i.e., viscosity, concentration, temperature, etc.).

INSTALLING THE OM500 ULTRASONIC HOMOGENIZER The OM500 Ultrasonic Homogenizer should be installed in an area that is free from ex- cessive dust, dirt, explosive and corrosive fumes, and extremes of temperature and hu- midity. - Page 13 7. OPERATING INSTRUCTIONS 7.1. 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 14 7.2. SETUP Connect the power cord into the receptacle on the rear of the OM500 Ultrasonic Homogenizer. Make sure the unit is switched off. Plug the electrical line cord into the electrical outlet. If the optional foot switch is used, insert the plug into the jack located on the rear panel.

ON key. The screen will display the power rating of the OM500 Ultrasonic Homogenizer and the following control parameters AMPLITUDE: Desired amplitude must be set in order for the OM500 Ultrasonic Homog- enizerto be operational. The other control parameters – Time and Pulse, do not have to be set for continuous operation. - Page 16 Also ensure that the probe tip is not touching the wall of the sample vessel. The OM500 Ultrasonic Homogenizer is now ready for continuous operation. To energize the ultrasonics, press the START key or the footswitch. To de-ener- gize the ultrasonics, press the STOP key or release the footswitch.
- Page 17 TIMER: Ultrasonics generates heat. Pulsing ultrasonics on and off helps to prevent heat build-up in temperature sensitive samples. In addition, pulsing may enhance processing by allowing the material to settle back under the probe after each burst. The ON and OFF pulse duration can be set independently from 01 second to 59 seconds. During the OFF portion of the cycle, the red indicator on the PULSE PULSE key will illuminate.
- Page 18 8. OPERATING INSTRUCTIONS 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 recom- mended sample volume range. This range may overlap with other probes. For example, the ½”...
- Page 19 How to prevent foaming (small sample issue) Foaming is a problem that often occurs with samples volumes below 1ml. The cause of foaming is generally 3 issues: amplitude is too high for a small volume, tip is too large for the volume, or the tip is not inserted to a proper depth. Tip depth The depth of the probe within the liquid is an important issue.
- Page 20 Long exposure to acids or caustics results in corrosion of metal parts or components. Check the power supply, converter, and cables periodically for any signs of rust or dis- coloration. If discoloration is found, move the OM500 Ultrasonic Homogenizer away from the source of the contaminant.
- Page 21 When excessive wear (corrosion/pitting of the probe tip) is detected the probe should be replaced with a new one. WARNING: Hand-tightening horns onto the converter is not sufficient; properly tighten them with the appropriate Wrench Set. See below the steps for attaching and detaching microtip probes: 9.2.
- Page 22 Note: When tightening a Microtip the tip must not be in contact with the work surface. Always have the tip extending off of the table or work surface to minimize stress to the tip. 9.3. SYSTEM CLEANING INSTRUCTIONS The power supply and converter may be cleaned using an acid-free cleaning solution (i.e.

Page 23: Troubleshooting
10. TROUBLESHOOTING Your OM500 Ultrasonic Homogenizerwas designed to provide you with years of safe and dependable service. Nevertheless, because of component failure or improper us- age, the possibility does exist that it might not perform as it should, shut down or stop working all together. -
Page 24: Converter Cooling
12. ADDENDUM 12.1. 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 25 Step Description Reference Attach a clean, dry, regulated compressed air source to one of the ¼” Air Cooling hose barbs. Note: The compressed air should be dry, oil free and filtered with a 5 micron filter. A 2nd hose must be attached to the 2nd ¼”...
- Page 26 12.2. COOLING AIR REGULATION AND ADJUSTMENT Adjust the regulated compressed air until the gauge indicates 10 ± 1 PSIG (approximately 4 CFM). The compressed air will flow into the converter and out through the outlet barb. Verify the compressed air is flowing out from the exhaust tube upon each use.
