1.1 Mode of operation
The ultrasonic generator transforms the absorbed mains energy (mains frequency 50 or 60 Hz)
into high-frequency energy with a frequency of 20 kHz. Thanks to the ultrasonic converter that is
connected to the ultrasonic generator, the high-frequency energy of the ultrasonic generator is
converted into ultrasound and thus into mechanical energy. This takes place with an e
ffi cient and
robust PZT ultrasonic oscillating system. Thus, mechanical de fl ections with a similar frequency
of 20 kHZ, which are transferred into the sonication medium as ultrasound waves with a high
power intensity, are generated on the tip of the probe. The amplitude is held constant by the
ultrasonic converter (AMPLICHRON
®
system), independently from the applied load, using a signal
feedback as long as the maximum power allowed is not exceeded. Thanks to these measures, the
reproducibility of the process parameters is guaranteed and validation of the process is supported.
Standard/booster horns with probes are mounted on the ultrasonic converter. These work
as mechanical transformers and enable a multiple mechanical ampli
fi cation of the ultrasonic
amplitude at the tip.
1.2 Purpose
SONOPULS ultrasonic homogenisers generate high-performance ultrasound with high intensities
and ultrasonic amplitudes, which are transferred into liquid media using working tools called
probes. They are used in laboratories, clinics, and in industrial research, and they perform diverse
tasks during sample preparation in Quality Assurance, scienti
fi c experiments, analyses, and in
pilot or short-series manufacture.
Application examples:
• Cell disruption for paternity tests
• Cell disruption (extraction of microorganisms, tissue cells)
• Homogenising of liquids
• Emulsifying hard-to-mix liquids
• Dispersion of agglomerates
• Acceleration of chemical reactions
• Degassing of
fl uids
• Sample preparation in environmental analytics (wastewater tests, soil samples)
• Sonochemistry
1.3 CE conformity
SONOPULS ultrasonic homogenisers are declared as IVD products and satisfy the CE marking
criteria for the European Union:
- IVD directive
- Low-voltage directive
- Electromagnetic compatibility directive
- RoHS - directive
in their currently valid versions.
A declaration of conformity can be requested from the manufacturer by providing the serial
number.
