The new SONICA S3 and S4 contains the best you can ask from ultrasonic cleaning equipment.

The state-of-the art ultrasonic generator incorporates a special ultrasonic oscillator using Sweep System Technology.

The diagram below shows the difference between a bath ultrasonic cleaner with conventional ultrasonic power generator (traditional system) and a new ultrasonic generator equipped with a special ultrasonic oscillator with the Sweep System Technology. The two systems are compared and show the different distribution of the ultrasonic waves into the cleaning liquid, their waveform oscilloscope view and finally the practical results obtained on a sample of aluminum.

How does the Sweep System Technology work in the ultrasonic cleaning ?

With Sweep System technology, the output frequency of the ultrasonic generator is modulated around a center frequency, so the ultrasonic transducers shift between 39 and 41 kHz. 
Sweep System Technology  offers the following advantages:

• Faster cleaning
• Damage free cleaning
• Increased distribution of ultrasound energy eliminating the standing waves
• Improved cavitation
• Facilitate the ultrasonic wave crossing through the mesh wire basket and the complicated objects to be cleaned
   

The degas function is used for degassing the cleaning liquids and allows some sound/chemical applications to be adopted, e.g. degassing of high polymer solvent (HPL). During this function, the detergent solutions are released from air bubbles which prevent effective propagation of the ultrasound waves. Whenever a new detergent or water is used, a degassing cycle of approximately two minuts is recommended in order to bring the air bubbles to the surface. Higher temperatures not only affect the quality of cavitation, but also help to degas the liquid and improve the chemical cleaning action.

A weak acid is an acid that dissociates incompletely in water and is a weak electrolyte.

A strong acid is an acid that dissociates completely in water and is a strong electrolyte.

A salt is an ionic compound formed in an acid-base neutralization reaction.

A reducing agent is a substance that cause a reduction by donating an electron.

A compound is a chemical substance composed of more than one kind of element.

it is the study of the composition, properties, and trasformation of matter.

The corrosion is the oxidative deterioration of a metal, such as the conversion of iron to rust.The rusting of iron requires both oxygen and water. The ultrasonic cavitation, in presence of strong acid or highly alkalyne solutions such as sodium hypochlorite, can cause highly accelerated corrosion even in stainless steel.
