Homogenisators Hielscher
Sonification direct, indirect or continuous Laboratory, pilot et industry
Applications of the sonification
Mixing, homogenization, dispersion, particle size reduction, deagglomeration, dissolution, degassing, extraction, cell lysis, chemical reactions, sonochemistry ... A complete sonifier includes an ultrasonic generator, a transducer, a sonotrode.
Sonification direct
In the case of a direct sonification, the sonotrode is directly in contact with the liquid.
The selection of sonifier power and sonotrode size is based on the volume of sample to be processed and the desired energy.
The greater the diameter of the sonotrode, the greater the ultrasonic power transmitted.
Titanium alloy is recognized as the best material for sonotrodes and is resistant to most liquids.
For some specific applications, we have sonotrodes in stainless steel, glass or ceramic. The maximum amplitudes of the sonotrodes in these materials are far less than the titanium sonotrodes.
The self-tuning of the system ensures then automatically increases a stability of the frequency.
It is possible to connect the sonifier to an analyzer thanks to the - UP200St-TD sonostep: A system for processing samples of small volumes before analysis: the three functions combined are sonication, agitation and pumping.
Sonification Indirect
In laboratories, it is often necessary to prepare several samples simultaneously under the same process and reproducibility conditions or to avoid contamination problems.
By this indirect sonication technique, no probe (sonotrode) is immersed in the sample in order to avoid cross-contamination and loss of sample.
The VialTweeter allows the simultaneous sonication of up to 10 tubes with the same intensity. Thus, VialTweeter is a reliable laboratory homogenizer for homogenization, emulsification, dispersion, deagglomeration, extraction, cell lysis, dissolution, but also degassing of liquids.
Another possibility for indirect sonication is the UP200St-TD with TD-CupHorn and TD_ViaHold11x5: A high intensity ultrasound bath for indirect sonication of 5 Eppendorf tubes.

Applications of ultrasonic baths
Cleaning, degassing, emulsion, dissolution, homogenization ... at laboratory scale and for the industry
Ultrasonic cleaning is today one of the most efficient and effective modern methods that eliminates clogging and other impurities from the most diverse objects in a record time and without risk of damage.
Ultrasound produces vibrations such that the liquid "breaks" (cavitation) and tiny bubbles of vacuum form.
When these implode, the impurities come off parts that will be carefully cleaned
Depending on the condition of the impurities, there is a suitable cleaner.
We have a wide range of cleaning products depending on the nature of the soil and the composition of the room. A good product also prevents the degradation of the stainless steel tank and increases its longevity. Specific detergents for laboratory and specific detergent applications for industrial applications.
-Standard equipment for laboratories from 0.8 to 90 liters, with or without heating function.
-Slow baths for production, workshops and service, from 3 to 18 liters
-Bands for industry up to 300 liters.
- Analogue ultrasonic devices for intensive cleaning, digital ultrasonics for laboratory, research and sonochemistry.
