The frequency of ultrasonic cleaning affects the quality and speed of ultrasonic cleaning.
All ultrasonic frequencies can generally be divided into low and high ultrasonic frequencies.
- Low frequency (20-40 kHz): Used for cleaning heavy contamination such as grease, oils, various dirt, dust, etc. These waves have stronger cavitation, which allows for more efficient and faster removal of dirt particles. This frequency is also suitable for use in laboratories for solution homogenization and has the widest range of applications.
- High frequency (40-100 kHz): Used for cleaning more delicate items whose structure is sensitive and not commonly used in everyday applications and industry, as these ultrasonic waves cannot remove heavier contamination.
Based on years of experience in manufacturing ultrasonic baths and other ultrasonic cleaning devices, as manufacturers, we have opted to produce ultrasonic baths that operate at frequencies from 37 to 40 kHz. This frequency range represents the upper limit of low frequencies.
The advantages of this frequency range of our ultrasonic baths are as follows:
- It provides sufficiently strong cavitation to remove even the most stubborn contamination;
- It offers an optimal density of ultrasonic waves per unit of surface area, thoroughly cleaning all surfaces of the items, and
- It significantly reduces the likelihood of damage to the items compared to a frequency range of 28 to 33 kHz.
