Instructions for use
• Do not touch the sonication vessels with the oscillating probe – probes and vessels could
be damaged.
• The recommended immersion depth for probes is of 10 - 20 mm, to prevent the aspiration and
mixing-in of air. If mixed-in air is desired, the probe may be immersed just a few millimetres.
In the case of greater immersion depths and/or the sonication of liquids with high viscosities,
the probe is more heavily damped. As a result, it is possible that the pre-set amplitude may not
be reached, especially with higher default settings (>50 %).
The reason is that the ultrasonic generator can no longer provide the required power, or the
power limit value has been reached (protective function).
• The immersion depth may not exceed 20 mm in the case of micro and tapered tips.
• When producing emulsions, the probe should be immersed to the level of the interface between
the liquids to be mixed.
• Do not use combustible solvents in open reaction vessels since the operating safety of the
homogeniser could be compromised.
• In order to shut down the device, disconnect it from the mains (pull the plug).

General use
Before starting use, the important instructions under Chapter 4.1 should be heeded!
Step 1:
Check the ultrasonic transducer
Verify that all connecting cables and couplings are correctly connected.
The
probe type must conform to the sonication volume, see table in Chapter 4.3.
The probe must be clean, faultless, and
fi
rmly mounted.
The
ultrasonic transducer must be securely a
ffi
xed.
Step 2:
Prepare the sonication
Prepare
the
sonication medium.
Position
the
sonication vessel below the ultrasonic transducer in such a manner that the probe
Set the immersion depth for the probe (approx. 1 - 2 cm).
