Hazards due to high temperature

The ultrasound bath, the sonication fluid and the sonication objects
can become hot during operation. Contact with these products may
cause burns. The temperature can be set at up to 80 °C.
Ultrasound energy warms up the sonication fluid even without
additional heating. Prolonged ultrasound operation can lead to very
high temperatures. In an ultrasound bath with heating, the set
temperature can be significantly exceeded by the energy of the
ultrasound.
• Observe the treatment times recommended by the manufac-
turer of the ultrasound preparation. Do not leave the ultrasound
switched on for longer than necessary.
• Do not reach into the sonication fluid with your hand. Remove
sonication objects with the insert basket or forceps.
• Allow the sonication objects to cool before touching them.

Non-aqueous fluids can heat up many times faster than water. A
possible flashpoint can be reached or exceeded after a very short
sonication time. In the case of high-boiling liquids, the bath tem-
