Why use an Ultrasonic Cleaner?

Some things are really difficult and time consuming to clean, such as machine parts with little nooks and crannies, delicate jewellery and murky laboratory glass cells.

Ultrasonic cleaners use ultrasonic waves to agitate a fluid. The agitation creates bubbles and pressure that make the cleaning more effective. It finds it’s way into all the tiny holes and cleans in more detail than our hands can clean.

For example, this technology is employed to clean soot from smoke damaged items, to clean smooth surfaces better, such as rust off a motor part, or to clean intricate detail on items such as watches and coins. Cleaning dirty items is easier and more efficient.

Other contaminants that you can clean off surfaces include lime scale, polish, wax, oil and blood.

Industries that find Ultrasonics Cleaners especially useful to deliver a cleaner product with less hard labour include jewellery, automotive, engineering, machine, laboratory and medical industries.

In laboratories, Ultrasonic Cleaners have extra uses. They are also used for degassing, dispersion of nanoparticles and emulsification of samples.

Most Ultrasonic Cleaners have a steel chamber, baskets you can remove, a heating element and a timer.

Which model should you choose?

  • Frequency – a higher frequency will clean gently and in more intricate detail and a lower frequency should be employed for coarser cleaning
  • Size – measure the items you would like to clean first and then select a size that will fit these items – small models are available for cleaning items such as jewelry and dental tools and larger models for machine parts, etc

Should you use a cleaning liquid, too?

In most cases, yes, the cleaning will be more effective. Which one you choose will depend on the item you are cleaning, e.g. ink off machine parts, blood off dental instruments, or grease off motor parts.

In a few cases, just water is used for cleaning more sensitive items, e.g. contact lenses.

Please email Selectech and let us know what you are cleaning, so that we can recommend a suitable cleaning solution for your application.

6 Things NOT to do with an Ultrasonic Cleaner

  1. Most items are cleaned in a hot solution (50 – 65°C), except for medical applications, which should be cleaned at less than 45°C, to prevent protein coagulation
  2. Do not use flammable cleaning materials, as they will be heated
  3. Do not expect ultrasonic cleaners to sterilize equipment – bacteria and viruses can remain after cleaning and a second step of sterilization will be required in some industries
  4. Do not place an item on the bottom of the chamber, always place it in a basket
  5. Most electronics can be cleaned with an Ultrasonic Cleaner and then dried quickly. Exceptions are gyroscopes, accelerometers, microphones and piezoelectric buzzers
  6. Absorbent items that can be damaged greatly by water and / or cleaners are not suitable for this type of cleaning, as they are immersed in water
