If none of these products are available, a neutral or mildly alkaline
product that does not destroy aluminium may be used. The product
must be approved by the manufacturer for use in ultrasonic baths.
Test results and documentation
Assuming constant test conditions, the test result is evaluated
based on the perforated surfaces of the foils. The perforated sur-
faces of all foils should have approximately the same reach and dis-

ensured through regular foil tests.
To document the test results, you can download a
documentation template here:

Here you will also find an application video.
Foils can also be archived if done in a suitable
manner (scanning, photos, etc.). This allows foils to be compared at
any time.

2. Degas the sonication fluid.
See chapter 5.7 Degassing sonication fluid .
3. Stretch aluminium foil (house-
hold foil, 10 μ m to 25 μ m thick)
over the foil test frame.
Depending on the tank size, it is
possible that the frame will pro-
trude outside the tank. Covering
the part of the foil test frame
that is covered by the sonication
fluid will be enough.
4. Place the covered foil test frame diagonally
in the centre of the oscillating tank. Fasten
it if necessary.
5. Switch on the ultrasound. Sonicate the foil
for at least one minute until visible perfora-
