Choosing the Best Ultrasonic Cleaner

Ultrasonic cleaning is used in a wide range of different industries and applications. That means there is no simple answer to the question of which is the best ultrasonic cleaner. The answer depends on what you want to achieve, so let's take a look at some of the things you need to consider.

Size Matters

One of the first things to think about is the size of the unit you're going to need. This is partly governed by where you're going to put it, but more important are the items you're going to be cleaning. It needs to be big enough to accommodate them comfortably so that they're fully immersed in the cleaning solution during the process. You can use the product pages of this website to check the dimensions of different models. Bear in mind that the basket used to hold the items will always be slightly smaller than the tank.


A major factor in choosing the best ultrasonic cleaner for any particular job is the operating frequency. Most sonic cleaning takes place between 33Khz and 45 Khz but there are also calls for higher frequency generators for a finer clean. The frequency determines the size of the bubbles created; higher frequencies make smaller bubbles so are better for small, delicate items, allowing the bubbles to get into all the crevices.

Some companies produce models that have a frequency sweep mode allow constant variation to avoid causing damage to electrical components and assemblies however this method is as efficient as the system we use. EJ use a constant power frequency which monitors the level of water, temperature and fluctuations to give the best available frequency at a given time. This gives your ultrasonic tank maximum efficiency in the majority of cases.

Our new digital circuit boards launching this year will give you even more control over your ultrasonic activity and monitor the activity with greater detail to give you the best and optimum clean available.

Dual-frequency models allow you to widen the range of items that can be processed.

Other Features

Having established the main criteria, there are a number of other features that can prove useful and which you need to consider. A thermostat allows you to accurately control the temperature of the cleaning solution. Similarly, a timer lets you set the length of the cleaning cycle and have the machine turn itself off at the end so that it doesn't need to be constantly watched over.

Some models also have a gentle agitation mode that oscillates objects in the tank in order to achieve more thorough cleaning. It's also possible to get cleaners with a pulse mode, delivering a burst of extra power for stubborn tasks.

Automation allows for full process control with automated fill ,Chemical dosing and accurate pick and place options. Automated systems also allow for greater repeatability and Whatever you need from an ultrasonic cleaner, use the product pages on the site to compare features and work out which is best for your needs.
