• Ultrasound energy warms up the sonication
fl
uid (even without additional heating).
- In the case of continuous sonication and/or covering the oscillating tank,
the
fl
uid temperature may increase more quickly and even rise above the
maximum adjustable value of the thermostat (80 °C). For this reason, check the
temperature when treating temperature-sensitive components.
- Non-aqueous
fl
uids can heat up many times faster than water. A possible
fl
ashpoint can be reached and/or exceeded after a very short sonication time.
In the case of high-boiling liquids (with and without a
fl
ashpoint), the bath
temperature can increase to >120 °C due to the energy input of the ultrasound.
This leads to irreparable damage to the ultrasonic bath.
• For an optimum bath temperature, observe the speci
fi
cations of the specimen
manufacturer!
• To protect the electronic components inside the ultrasonic bath, the ultrasound
output is reduced upon reaching a critical temperature in order to inhibit a further
increase in the interior temperature.
• The
fl
uid in the oscillating tank may not exceed a maximum operating temperature of
100 °C.
• Cover the ultrasonic bath when in continuous operation so that not too much bath
liquid evaporates.
• For safety reasons, ultrasonic baths should be covered when not in operation, to
prevent operating and external personnel from inadvertently coming into contact with
the bath liquid and being injured by liquids that are still hot.

General use
Step 1:
Fill oscillating tank
The oscillating tank is
fi
lled with water and a suitable preparation to reduce the surface
tension, see chapter 7.3.
Fill 1/3 of oscillating tank with water.
Add dosed preparation to the oscillating tank.
Fill carefully up to the
fi
lling level mark, avoid the formation of foam as much as
possible.
Step 2:
Degassing the
fl
uid
Freshly-
fi
lled bath
fl
uid or
fl
uid that has remained in the oscillating tank for a longer
period of time must be degassed prior to use. See also chapter 4.3.1.
Remove basket and other accessories from the oscillating tank.
Place lid on top.
Turn on the ultrasound with the turning knob and sonicate for 30 min for degassing,
see chapter 3.1.1.
