4 Use
4.1 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 HF generator
can no longer provide the required power, or the power limit value has been reached (protective
function).
• 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).
4.2 General use
Before starting use, the important instructions in 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 af fi xed.
Step 2: Prepare the sonication
 Prepare the sonicating medium.
 Position the sonication vessel below the ultrasonic transducer in such a manner that the probe
does not come in contact with the vessel.
 Set the immersion depth for the probe (approx. 10 -20 mm).
 If needed, connect the temperature sensor and position it in the medium.
