Ultrasonic Homogenizer is nowadays a primary requirement for materials synthesis laboratories. Almost all materials synthesis methods, in some of the stages of their processes, somehow deal with mixing, homogenizing and preparing of emulsions and suspensions. In summary, homogenizing is creation of turbulence in a liquid medium which overcomes the surface tensions of substances with low solubility in each other, and as a result leads to the formation of stable emulsions or suspensions. The applications of ultrasonic homogenizer, however, can be wider; mixing chemicals for reaction with each other, separation of nanoparticles, dispersion and prevention of agglomeration, crashing and grinding, and cell disruption and extraction are some applications of ultrasonic homogenizing. Homogenizing is also used in the different industries such as food, chemical, pharmaceutical, oil and gas.
Homogenizing processes could be classified in three different subgroups which include ultrasonic homogenizing, pressurized homogenizing and mechanical homogenizing. An ultrasonic homogenizer is made up of three major parts, i.e. generator, transducer and booster. The ultrasonic generator converts the input single-phase electricity of 220 VAC, 50-60 Hz into high-frequencies required for the ultrasonic system (15 to 40 kHz). The ultrasonic transducer transforms the electrical oscillations to the mechanical energy through a piezoelectric or magnetic coil. The booster, that is sometimes called horn, amplifies the vibration amplitude and transfers it to the probe. Because the probe is in direct contact with the environment, it is usually made of wear and corrosion resistant materials.
The ultrasonic homogenization by creating the intense sonic pressure waves in a liquid medium leads to the production of turbulent flows, and under the right conditions, causes rapid formation of microbubbles through a phenomenon known as cavitation. The growth and subsequent implosion of bubbles can generate shock waves with enough energy which can even break the covalent bonds.
Another advantage of ultrasonic homogenizer is the ability to fully control operational parameters which govern the cavitation. Being able to control frequency, amplitude and pressure as the most influential variants, the homogenizing process is readily controllable and gives valid and repeatable results. This issue is important in generalizing the process conditions from laboratory scale to industrial scale.    
Ultrasonic Homogenizer provided by the manufacturer is an instrument to fulfill all the needs of researchers and industrialists in related fields. Some of its applications are as follows:
  • Production of nanomaterials 
  • Improving the extraction process of herb extracts
  • Acceleration of chemical reactions
  • Preparation of stable emulsions and suspensions
  • Dispersion of nanoparticles in liquids
Four different models of ultrasonic homogenizer device have been offered by manufacturer. Among these models, APU500a-015 is the most comprehensive ultrasonic processor used to disperse nanoparticles; this model is a programmable laboratory device that can be used in projects as well as the implementation of innovative research ideas. This device operates at a frequency of 20 kHz and can also be used by applying different output powers with different intensities. All the Ultrasonic Homogenizer models offered by this company are able to adjust the reaction time. Details of technical specifications about four different models are presented in the following Table.

Many of the synthesis processes of nanoparticle and nanostructured materials rely on homogenization and in some of the early stages of their processes need to be prepared as emulsions and suspensions. Thus, the application of ultrasonic homogenizer in production of nanoparticles, nanostructured materials and generally, in nanotechnology is very broad and fundamental.  
  • Before connecting the device to power supply, make sure that the power supply is compatible with the required voltage for the device.
  • Make sure that the device installation site provides proper ventilation.
  • Place the device at an appropriate distance from the noise-sensitive electrical systems.
  • After each session, clean the probe tip with a soft cloth to avoid any surface scratches or pitting.
  • Before each session, make sure that the probe is tight and fixed in its place, and, if necessary, tighten it. 
  • Always keep in mind that all contact surfaces, especially the surfaces between the probe and the horn, should be kept clean.
  • Contact of probe with acidic or base solutions should be avoided as much as possible. If it is impossible, minimize the contact time to delay the corrosion/erosion phenomena.
  • For more details on how to use the device, refer to the device catalog and user guide.
  • Make sure that the connection of electrical cables is correct.
  • Ensure that the earth connection cable is right. 
  • Avoid any contact with oscillating parts during operation.
  • Avoid using the flammable solutions in open containers, otherwise safe operation of the device cannot be guaranteed.
  • In case of using a sound abating box, never allow the solvent fumes to accumulate inside the box, especially if they might be poisonous or combustible.
  • Do not let the probe vibrate in the air for more than a few seconds.
  • Due to the sensitivity and accuracy of the probe, transport it carefully.
  • Avoid any contact between the probe and the container during operation.
  • Bear in mind that occurrence of solution splashing during operation is possible.
