5.1 Immersion depth notes
The recommended immersion depth for probes is 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.
When producing emulsions, the probe should be immersed to the height of the
surface separating the liquids to be mixed.
5.2 Preselect parameters for sonication
5.2.1 Set amplitude or power
Information
In the case of greater immersion depths or the sonication of liquids with high vis-
cosities, the probe is more heavily damped. As a result, the preset amplitude may
not be reached.
The device can regulate the emitted ultrasonic power so that either a set ampli-
tude is kept constant or a set power is kept constant. The amplitude is given in %.
The absolute value of the amplitude depends on the combination of standard
horn or booster horn and probe. The power is specified in watts and depends on
the respective ultrasonic converter.
1. On the startup screen, tap "Parameters".
2. Tap "Ampl./Power".
3. Tap "Amplitude" if sonication is to be carried out with a constant amplitude, or
"Power" if sonication is to be carried out with a constant power.
4. Select the desired value for amplitude or power. You can move the bar of the
selected setting parameter or enter a numerical value.
5. Confirm your entry with the "Confirm/Save" button.
With amplitude regulation, the amplitude is kept constant. The power can vary
depending on the condition of the medium. When the respective maximum power
is reached, the amplitude is reduced.
Power control keeps the power constant. The power can vary depending on the
condition of the medium. When the respective maximum amplitude is reached,
the power is reduced.
