ULTRASONIC DISPERSER
Designation
The sonicator is used to generate ultrasonic vibrations in liquids.
The system can be used in production of suspensions or emulsions of different substances, rinsing of small articles from mechanical impurities, extraction, dispersion, and in sonochemistry, as well as in processing of samples from fiber-like, crystal-like, powder-like and other substances during electron-microscope research.
Applications
Chemistry, sonochemistry:
- acceleration of sonochemical reactions;
- improvement of reactive ability in metallic surfaces;
- scission of high-molecular compounds (depolymerizing);
- catalytic effect in reactions with powders (for instance, catalytic effect of Nickel powder is intensified under ultrasound by several orders of magnitude);
- cracking processing of paraffins into smaller fragments under room temperature;
- increasing the yield rate in Ulmann and Wurtz reactions, as well as in other types of reactions.
Medicine:
- fast breakage of bacteria, among which are Acetobacterxylinum, Actinomyces, Bacillus subtilus, Candida albicans, Erythrozytes, Eukaryotic cells, H. Ep. 2-cells, Helicobacter pylori, Saccharomyces cerecevisae, Lactobacillus, Staphylococcus aureus, Steptococcus;
- simplification of the blood test for Stomafree hemolysate – the processing time is reduced from 30 min down to 5 s;
- breakage of the DNA chains;
- separation of encymes from mitochondria;
- acceleration of Misfolding prions production in medical research;
- cell disruption.
Technology and analysis:
- production of stable and fine emulsions;
- production of stable and fine suspensions, including suspensions of nanoparticles;
- preparation of soil samples to identify the presence of hydrocarbons, polycyclic aromatic hydrocarbons;
- homogenization of samples of wastes to decide on their salvageability;
- freeing of gas from liquids,
- purification and degreasing of surfaces

Operation principle
The sonicator has the following principle of operation: the piezoelectric emitter converts electrical oscillations, generated by the transistor generator, into elastic mechanical vibrations at a corresponding frequency. These vibrations are transferred to the working medium through a waveguide.
The impact on the physico-chemical processes in liquids is achieved mainly due to the secondary acoustic effects, namely cavitation and acoustic flows.
