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.
Cooling the sample buy submerging the beaker or tube in ice will help to cool the probe and
converter. Chillers are also commonly used. If you have an application that requires greater than
15 minutes of continuous processing (at high amplitude) there is potential for the probe/converter
assembly to increase in temperature.
The general rule is that if the converter is warm to the touch it should be cooled. In addition to
cooling the sample you must cool the converter with compressed air. Each converter has 2
threaded ports for air cooling. 10psi of dry, clean (5 micron filtered) air is required. One port is
attached to the air source and the other port remains open as a vent.
1
Feel for holes under the label on the end of the
converter. Use a razor to expose both holes.
2
Attach fittings.
Black fittings shown come attached to the
converter in a small clear bag.
Replacement fittings are available at no charge
upon request.
