1.1 Mode of operation
Ultrasonic baths use the effect of cavitation. Under their oscillating tank bottoms they
contain piezoelectric transducers, the energy of which is transferred to the bath liquid with
ultrasound frequency as mechanical oscillations. As a result, microscopically small bubbles
are continuously formed in the bath liquid, which release energy upon imploding and
generate local microcurrents. This process is called cavitation.
1.2 Purpose
General use
The SONOCOOL ultrasonic bath is intended for use in analytical labs as well as for
industrial and scientific research and also in pathologies. With the bath it is possible to
use the catalytic effect of ultrasound for processes during which simultaneous cooling
is required. Heat-sensitive samples are protected by the cooling function and process
sequences can be designed to be faster and more effective than customary procedures.
Cooling is conducted automatically, the ultrasound can be separately switched on.
In addition to the temperature, the runtime can be set for up to 99:59:59 hours. In addition,
four different levels of ultrasonic power can be selected. The ultrasonic bath is table-
top operated using the keys on the front of the device, and is designed for unmonitored
continuous operation.
Caution!
The sonication takes place indirectly in inset beakers.
Ultrasound cleaning directly in the contact liquid is not allowed with the SONOCOOL.
In-vitro diagnostic use of the bath
The SONOCOOLcan be used for in vitro diagnostic treatment or laboratory procedures
(e.g. bone decalcification) in which medical information is gathered from the treatment of
organic or inorganic material. In this case, it is classified and treated in accordance with
Directive 98/79/EC on in vitro diagnostic medical devices (IVD).
1.3 CE conformity
The ultrasonic bath is declared as a IVD device and satisfies the CE marking criteria for the
European Union:
- IVD Directive
- Low-Voltage Directive
- Electromagnetic Compatibility Directive
- RoHS Directive
in their currently valid versions.
The declaration of conformity can be requested from the manufacturer.
