Notes - Temperature and heating
• Warmed-up
fl
uids intensify the ultrasound effect. Experience has shown that the best
results are obtained with a bath temperature of 50 to 60°C. At higher temperatures,
the effect of the ultrasound cavitation decreases again, however
1
.
• In order to save time during use, the bath
fl
uid may be preheated during degassing.
• Ultrasound energy warms up the sonication
fl
uid (even without additional heating).
- In case of continuous sonication and/or covering the oscillating tank, the
fl
uid
temperature will increase, even rising above the value set on the thermostat.
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, adhere to the speci
fi
cations of the specimen
manufacturer!
• To protect the electronic components, 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.

General use
Step 1:
Filling the oscillating tank
The tank is
fi
lled with water (tap water or deionised water) and with a preparation
containing surfactants to reduce the surface tension, see chapter 7.2.
With the device switched off.
Fill oscillating tank with 2 litres of water.
Add dosed cleaning agent.
Carefully
fi
ll it up with 7 or 16 litres of water, taking care to avoid foaming as much
as possible.
