Ultrasonic Cleaner for Ultrasonic Cleaning

Ultrasonic cleaning of medical instruments, with a special ultrasonic cleaner, is carried out on the principle of cavitation. Because this process is very gentle on materials, ultrasonic cleaning can be applied for many surgical instruments. One can use either a cleaning agent or a combination preparation of cleaner and disinfectant in the ultrasonic cleaner.

Not only is cleaning and disinfecting with an ultrasonic cleaner time saving, but it is also quite safe. Since the staff does not have to manually clean the instruments, they also do not come into direct contact with potentially infectious germs. Furthermore, instrument prep with an ultrasonic cleaner is much more effective than cleaning by hand, considering that the ultrasonic waves penetrate even the smallest nooks and crannies of the items being cleaned.

Basic Cleaning with Ultrasound Waves

Ultrasonic cleaning functions on the principle of so-called  cavitation. That means that negative and positive pressure waves are created within the ultrasonic cleaner, building up small, gas-filled bubbles on the instrument surfaces and then bursted. The emergence and bursting of these gas-filled bubbles is what cleans the surface of the instruments. Some ultrasonic cleaners can also be heated, which positively influences the cleaning affect.

In general, cleaning with an ultrasonic cleaner is more thorough than cleaning by hand as the ultrasound waves can also get into the smallest crevices that a brush just cannot reach.

An Ultrasonic Cleaner Consists of a Trough, Ultrasonic Oscillators & Transducers

An ultrasonic cleaner is composed of a metal trough, which is equipped with ultrasonic oscillators or transducers. Before proceeding with the ultrasonic cleaning, water and suitable additives are placed into the machine.

Some suppliers offer combination preparations of cleaner and disinfectant, which can also be used in an ultrasonic cleaner.

By using combination preparation, the cleaning and disinfection process can be carried out in a single step. This saves valuable time and costs. Furthermore, the risk of infection for staff is even lower.

In order to allow for an optimal clean, the "soft cavitation" must be prevented. That only works when the liquid, which is found in the ultrasonic cleaner, is degassed. For this purpose, some ultrasonic cleaners include the important degassing function.
