Care of MICROPROBE Tips
Proper care of MICROPROBE tips is essential for good performance and long service life.
Tightness of the probe, cleanliness of the mating surfaces and condition of the probe tip are
all very important to overall performance. The probe tip is continuously subjected to intense
shock waves, which cause cavitational erosion of the probe's tip. Keeping the tip face
smooth and polished will significantly improve sonication efficiency and increase the useful
life of the probe. The following maintenance procedures should be performed weekly:
x
Check the tightness of the probe periodically with the open-end wrenches provided.
x
Keep the stud threads and the mating surfaces between the probe and the (black) front
driver clean and dry.
x
Check the probe tip for signs of cavitational erosion and pitting.
x
Polish the probe tip with a very fine emery cloth or sandpaper (#600) to remove any
surface scratches or pitting.
x
Do not file or grind the probe tips as this could bend or break them.
x
Replace probes periodically, especially if they no longer tune properly, are badly pitted or
eroded, or if they are bent or cracked.
