1.1
Mode of operation
The HF generator transforms the absorbed mains energy (mains frequency 50 or 60 Hz) into
high-frequency energy with a frequency of 30 kHz. Thanks to the ultrasonic transducer that is
connected to the HF generator, the high-frequency energy of the HF generator is converted into
ultrasound and thus into mechanical energy. This takes place with an ef
fi
cient and robust PZT
ultrasonic oscillating system. Thus, mechanical de
fl
ections with a similar frequency of 30 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 transducer
(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.
Probes are mounted on the ultrasonic transducer. These work as mechanical transformers and
enable a multiple mechanical ampli
fi
cation of the ultrasound amplitude at the tip.
1.2
Purpose
SONOPULS ultrasonic homogenizers generate high-performance ultrasound with high intensities
and ultrasonic amplitudes, which are transferred into liquid media through working tools known as
probes. They are used in laboratories, clinics, and in industrial research, and in the process they
perform versatile 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)
• Homogenizing of liquids
• Emulsifying hard-to-mix liquids
• Dispersing of agglomerates
• Accelerating chemical reactions
• Degassing of
fl
uids
• Sample
preparation in environmental analytics (wastewater tests, soil samples)
• Sonochemistry
SONOPULS ultrasonic homogenizers are also used for in-vitro diagnostic lab procedures, to
procure information from the handling of organic materials with ultrasound. Therefore, they are
classi
fi
ed and treated in accordance with the Directive 98/79/EC on in-vitro diagnostic medical
devices.
1.3 CE
conformity
SONOPULS ultrasonic homogenizers are declared as IVD products and satisfy the CE marking
criteria for the European Directives:
- IVD directive
- Low-voltage directive
- Electromagnetic compatibility directive
in their currently valid versions.
A declaration of conformity can be requested from the manufacturer by providing the serial
number.
