Ultrasonic Homogenizer has today become of primary necessity for every material synthesis laboratory. Almost all material synthesis methods and procedures, in some of their processes, somehow deal with mixing, homogenizing, and preparation of emulsions and/or suspensions. Homogenizing is concisely described as an agitation-making process, in which the resulting turbulence in a liquid medium helps overcome surface tensions of those matters with low solubility in each other, so that an abiding emulsions and/or suspensions could be formed. The applications of ultrasonic homogenizer, however, cover wider domains; Mixing chemicals for reaction purpose, separating nanoparticles, dispersing and preventing from agglomeration, crashing and grinding, destructing and cellular extraction are some of examples of ultrasonic homogenizing usage. Homogenizing is also used in the different industries of food, chemical, pharmaceutical, oil and gas.
Homogenizing processes could be categorized in three subgroups which include ultrasonic homogenizing, pressurized homogenizing and mechanical homogenizing. The ultrasonic homogenizer apparatus consists of three main parts including the generator, transducer, and booster. The generator's task is to transform electrical frequency from 50-60 Hz to those high electrical frequency required in ultrasonic system, ranging from 15 to 40 kHz. The transducer's task is to transform the electrical oscillation to the mechanical oscillation, either by employing piezoelectric technology or using magnetic coils. A booster, that is sometimes called horn and/or probe, is tasked with amplifying and transferring oscillation amplitude into the probe. Since the probe itself is in intimate contact with the medium, it is usually made of wear and corrosion resistance materials.
Releasing intensively compressive waves into the medium, the ultrasonic homogenizer can generate turbulence, and under some proper conditions, cause to rapid formation and explosion of microbubbles through a process called cavitation. This bubbles explosion could generate shock waves and shear forces, strong enough to break down even 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 becomes much more important when one consider to generalize the experimental conditions to a wider area of industrial scales.
Ultrasonic Homogenizer provided by Adeeco Company is an equipment fabricated to meet all the needs of researchers and industrialists. Some of the its applications are;
  • Nanomaterials processing
  • Improvement of the extraction process of herbal extracts
  • Stable product of emulsions out of insoluble liquids
  • Dispersing nanoparticles in liquids
The manufacturer offers four variants of the ultrasonic homogenizer. The most comprehensive ultrasonic processor for dispersing Nano-particles is APU500a-015 which is a programmable small-scale laboratory apparatus and can be utilized in projects and also in making innovative research idea work. This device is set on 20 kHz working frequency and is capable of applying different output powers with different intensity. All the Adeeco Ultrasonic Homogenizers is also capable of adjusting the reaction time. More details about APU500a-015 and other models have been shown in the Table.
Many of material synthesis processes which also encompass the nanoparticles and nanostructured ones, deal with homogenizing, and in some of the primary steps in their processes need to be prepared as an emulsion and/or suspension. So the application of ultrasonic homogenizer lies at the very heart of nearly all nanoparticles and nanostructured material synthesis.
  • Before connecting the power, ensure compatibility of the available power with the mains voltage on the generator base or label.
  • Ensure proper position of apparatus for good ventilation.
  • Place and use the apparatus at an enough distance from electrical noise-sensitive systems
  • Polish the probe tip after each session with a very fine emery cloth to remove any surface scratches or pitting.
  • Before each session, check the tightness and fixing of the probe to the booster horn, and if necessary tighten it.
  • Always remember that all the mating surfaces especially the one between the horn and the tip must remain clean.
  • Avoid and/or minimize the probe's exposure time to acids or caustic as possible as you can, in order to mitigate corrosion/erosion phenomena.
  • Frequently check the integrity of electrical connectivity
  • Ensure the good connection of earth cable.
  • While operating, do not touch any oscillating part during the process.
  • Do not use combustible solvents in open vessels because the operational safety of the
  • homogenizer cannot be guaranteed.
  • In case of using a sound-proof box, never allow the solvent fumes to be confined inside the box, especially if the fumes is suspected to be poisonous or combustible.
  • Do not let the probe vibrate in air for more than just a few seconds
  • Owing to the precision sensitivity, handle the probes with care.
  • It is strongly advised to avoid any contact of the vessels with the oscillating probe.
  • Never leave the equipment running without any supervision.
  • When apparatus operating, mind danger of splash.
