Ultrasonic homogenizers 

SONOPULS Ultrasonic homogenisers are mainly used for homogenising,  desagglomerising, emulsifying, suspending, acceleration of chemical reactions as well
as for disruption of cells, bacteria, fungi or spores. Significantly reduced processing times and quickly available results make the ultrasonic homogenisers indispensable for modern processes and in analysis. Using ultrasonic homogenisers certain substances can be selectively destroyed, tedious preparation processes can be shortened and results of many reactions are improved. When sonicating samples not only μm particles
can be achieved but also particles in nm range! With many years of experience in the field of ultrasonic homogenisers we assist you in your specific application.

SONOPULS homogenizers with amplitude regulation 10 to 100 % and actual value display, pulse rate, AMPLICHRON® mode (guarantees a constant amplitude in independence of changing conditions), integrated timer, remote control. All units have a CE mark and are medical products according to the guideline for in vitro diagnostics 98/79/EG.

Fields of application:

- Disruption of cells, bacteria, virus, tissue (cell disruption)
- Production of finest emulsions
- Homogenization of substances
- Sample preparation for HPLC
- Degassing of fluids
- Sample preparation for particle size analysis 
- Acceleration of chemical reactions
- Waste-water analysis

Typical areas of application
• Disruption of cells without distroying the cell content
• Disruption of tissue, also mixed tissue
• Emulsifying of hardly mixable liquids, e. g. oil and
water, particle size in nm range
• Deagglomeration of nanoparticles in material
research (nanostructurised material) in medicine,
biotechnology, automobile industry
• Acceleration of chemical reactions
• Dispersing

• Preparing samples for grain size determination or
environmental analysis
• Homogenising of cheese samples for determination
of nitrates

Biochemistry – Biology – Medicine
• Sonication of small high-quality samples for analysis
like EIA or RIA
• Due to high amplitudes, disruption of either highresistant
bacteria, cells are tissues is possible.
Indirect processing of samples in cup booster BR 30
or in cup horn BB 6 are recommended to avoid
• Detection of prions by cyclic amplification of protein

Chemistry – Sonochemistry
• Acceleration of chemical reactions or destroying of
highly-molecular compounds

Pharmacy – Cosmetics
• Production of larger volumes of long lasting emulsions,
e g. lotions and production of antigens,
vaccines or liposomes

Essential aspects for choosing the appropirate
SONOPULS ultrasonic homogeniser

What is the difference between ultrasonic
homogenisers and ultrasonic baths?
The power [W] of ultrasonic baths is fixed. The power density [W/l] is relatively low.
Ultrasonic homogenisers have an adjustable power [W] and produce very high power densities [W/l]. Probes with a defined radiating surface guarantee reproducible results.

What is more important when choosing the appropriate
device – power rating or amplitude?
Power output [W] is not the sole criterion for selecting the ultrasonic homogeniser. This value only indicates the power of the ultrasonic generator but not the energy delivered into the sample. The amplitude at the radiating surface of the probe is the determining factor while considering the sample volume. SONOPULS homogenisers provide higher amplitudes than comparable devices in the market due to an optimal matching of all components.
