Laboratory ultrasonic cleaners are specifically designed equipment for cleaning laboratory instruments, containers, tools, etc. They utilize the "cavitation effect" generated when ultrasonic waves propagate through the cleaning liquid medium to achieve the cleaning purpose. Additionally, they can meet experimental needs such as extraction, dispersion, dissolution, and emulsification.

Ultrasonic frequencies suitable for laboratories include conventional mid-to-low frequencies like 28KHZ and 40KHZ, as well as high frequencies: 60KHZ, 80KHZ, 120KHZ, 200KHZ, etc. The Yunyi Laboratory Ultrasonic Cleaner series offers multiple frequency options (28, 40, 68, 80, 120, 132, 175, 200KHz).

Working Principle of Ultrasonic Cleaners

Ultrasonic cleaning is based on the physical effect of "cavitation" when ultrasonic waves propagate through the cleaning liquid medium. The ultrasonic generator produces electrical energy with a frequency higher than 20KHz, which is converted into ultrasonic energy by the transducer and transmitted into the cleaning medium. When the intensity of the ultrasonic field exceeds the cavitation threshold of the cleaning medium, numerous expanding "cavities" rapidly form in the cleaning liquid due to ultrasonic negative pressure. During ultrasonic positive pressure, these "cavities" are intensely compressed, creating microscopic shockwaves and high-speed jets that act on the surface of the object being cleaned, causing contaminants to be quickly crushed and dislodged.

Materials Used in Laboratory Ultrasonic Cleaners
Standard configuration includes an integrally stamped stainless steel tank, ranging from 3.2L to 30L, with a stainless steel body material. Additionally, custom multi-frequency machines with different inner tank sizes are supported.

Parameters of Single-Frequency Laboratory Ultrasonic Cleaners:

Features and Advantages
Excellent Cleaning Effect: Ultrasonic cleaners offer high cleaning efficiency and fast cleaning speed, especially for blind holes and objects of various geometries, achieving cleaning results that other methods cannot match.
Multi-Frequency Cleaning: Triple-frequency ultrasonic cleaners typically feature three ultrasonic cleaning frequencies (e.g., 40KHz, 80KHz, 120KHz), which can be combined in various ways to achieve single-frequency, dual-frequency, or triple-frequency cleaning modes, meeting diverse cleaning needs.
Strong Protection: To prevent instrument damage, hidden heating methods are used to achieve automatic heating, with adjustable cleaning temperatures. Additionally, ultrasonic power can be adjusted in real-time via a touchscreen to adapt to different cleaning requirements.
Wide Application: Triple-frequency ultrasonic cleaners are widely used in various industries such as surface coating treatment, machinery, electronics, semiconductors, etc., capable of cleaning objects of various materials and shapes.
