Conducting the foil test
1. Fill 2/3 of the oscillating tank with water and a suitable
ultrasound preparation in the dosage specified by the man-
ufacturer.
2. Degas the liquid: < 10 l - 10 min and > 10 l - 30 min
(see user instructions.)
3. Stretch aluminium foil (household foil with a thickness of
10
v
m to 25
v
m) over the wire frame (stainless steel).
Depending on the tank size, it is possible that the frame
protrudes from the tank.
Covering the portion of the frame that is submerged will
suffice.

5. Switch on the ultrasound and sonicate the foil for at least
one minute until visible perforations or holes are produced.
With sturdier foils (thicker or coated ones), the sonication
time can last up to 3 minutes.
6. Switch off the ultrasound, take the foil out and let it dry.
7. The foil must be perforated, otherwise contact the manu-
facturer.
