With the continuous advancement of technology, the application fields of ultrasonic cleaners are expanding, and their functions are becoming increasingly diverse. Among these, "dual-frequency" has become a feature that many users pay attention to when making a purchase. So, what exactly does "dual-frequency" mean in an ultrasonic cleaner, and how does it differ from single-frequency devices?

A single-frequency ultrasonic cleaner can only operate at one fixed frequency, making it generally suitable for cleaning specific types of items. In contrast, a dual-frequency ultrasonic cleaner has the capability to switch between two frequencies, allowing users to flexibly choose the more suitable cleaning frequency based on the material of the items being cleaned and the type of contaminants.

Common dual-frequency combinations on the market include 28kHz/45kHz and 45kHz/80kHz. In comparison, most standard ultrasonic cleaners still use a single-frequency design, such as the common 28kHz, 40kHz, or 80kHz models, which are widely used in industrial, household, and commercial settings. However, in specialized environments like laboratories and medical fields, where tasks such as emulsification, dispersion, solubilization, extraction, or accelerating chemical reactions are involved, the requirements for cleaning precision and adaptability are higher. As a result, dual-frequency ultrasonic cleaners are often preferred.

In summary, the dual-frequency design offers greater flexibility and applicability to the cleaning process, enabling one device to handle a wider variety of cleaning tasks. We hope this explanation gives you a clearer understanding of the differences between single-frequency and dual-frequency ultrasonic cleaners. When making a purchase, it is recommended to consider your specific cleaning needs and usage scenarios to select the appropriate frequency type and achieve optimal cleaning results.
