2 Safety
2.1 Use of the device
The device is used in laboratories, clinics and in industrial research. It performs
diverse tasks during sample preparation in Quality Assurance, scientific experi-
ments, analyses, and in pilot or short-series manufacture.
Examples of applications are:
• Disruption of cells, bacteria, viruses, tissue
• Production of the finest emulsions
• Homogenising of substances
• Degassing of liquids
• Sample preparation for the grain size analysis
• Acceleration of chemical reactions
• Sample preparation for sewerage analysis
2.2 Explosion hazard
Do not use the device with combustible liquids as a sonicating medium.
Combustible vapours may be generated when flammable liquids are sonicated.
Vapours may ignite, e.g. on electrical components, resulting in an explosion.
Do not use combustible solvents in open sonication vessels, as the operational
safety of the device could be compromised. Safe extraction of combustible
vapours must be guaranteed.
2.3 Hazards due to high temperature
Ultrasound heats up the sonicating medium. The device, the sonicating medium
and the sonication vessel can become very hot during prolonged ultrasound oper-
ation. Contact with these products may cause burns.
• Do not leave the ultrasound switched on for longer than necessary.
• Allow the probe and sonication vessel to cool down before touching them.
Non-aqueous liquids can heat up many times faster than water. A possible flash-
point can be reached or exceeded after a very short sonication time. In the case of
high-boiling liquids, the temperature can rise to over 120 °C due to the energy
input of the ultrasound. This can lead to fires and severe burns.
