Performance
Check your cleaner periodically to test the level of activity of the
ultrasonic cavitation. Frequency of testing will depend on your use of the
cleaner, however, we suggest running this test monthly.
Glass Slide Test
You will need the following equipment:
• Frosted microscope glass slide (1” x 3”), such as ESCO #2951F, or
equivalent;
• No. 2 lead pencil; and
• General purpose dish detergent.
Test procedure:
1. Prepare a fresh solution with general purpose dish detergent
(concentration 1%) and warm tap water (120º - 140ºF).
2. Fill the cleaner to within one(1) inch of the tank top.
3. Turn the ultrasonics on for at least five minutes to allow for degassing.
4. Prepare the glass slide by first wetting the frosted portion with tap
water.
5. With the No. 2 pencil, on the frosted portion make an “X” from corner
to corner.
6. Immerse the frosted end of the slide into the solution. Hold the slide
vertically and center it in the solution.
7. Turn ultrasonic switch to “On”.
