7.1 Maintenance and Troubleshooting

The SLPt Cell Disruptor is a self-contained system that requires no internal servicing, except for a protective
fuse, and there are no user serviceable parts inside the unit. The ultrasonic tooling (microtips) may require
periodic inspection and maintenance to ensure optimum performance. The tooling components are subject
to wear and may require replacement after a period of time, depending on the applications.
If you have a problem operating your unit, refer to Table 7.1 'System Trouble Analysis Chart' on page4 to
locate the symptom that most clearly describes your problem.
Tip Erosion
Microtips can erode. Tip erosion is a side effect of the cavitation process that occurs when liquids are
exposed to ultrasonic energy. The rate of erosion depends on the intensity of power applied, the corrosive-
ness of the liquid being treated, and the amount of use.
Periodically inspecting the tip will help you recognize erosion early. As erosion progresses, the color of the
tip changes from its original polished appearance, first to light grey and then to dark grey. Concentric rings
begin to appear, and finally the tip becomes rough and pitted, resulting in loss of power output. As it erodes,
the tip can also introduce metal particles into the solution, causing it to darken or discolor.
Eventually, erosion may become significant, at which point the tip will require replacement.
