Laboratory ultrasonic cleaners are devices that utilize ultrasonic technology for cleaning, widely used in laboratories due to their high efficiency, environmental friendliness, and non-contact cleaning characteristics.
The working principle of laboratory ultrasonic cleaners is primarily based on the unique physical effect of "cavitation" when ultrasonic waves propagate through the cleaning liquid medium. The ultrasonic generator produces high-power electrical energy at ultrasonic frequencies above 20KHz, which is converted into high-power ultrasonic energy through the inverse piezoelectric effect of the ultrasonic transducer and transmitted into the cleaning medium. The ultrasonic waves undergo tens of thousands of cycles per second of negative pressure expansion and positive pressure compression in the cleaning liquid, generating countless "cavities" and forming high-frequency microscopic shockwaves. These shockwaves can penetrate into the tiny gaps and grooves on the surface of objects, stripping away dirt and impurities.

Ultrasonic frequencies suitable for laboratories include conventional mid-to-low frequencies such as 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).
Laboratory ultrasonic cleaners are suitable for cleaning a variety of items, including but not limited to:
Various instruments in the laboratory, such as microscope lenses, spectrometers, etc.
Common laboratory glassware like test tubes and beakers.
Surgical instruments, endoscopes, and other medical devices used in hospital operating rooms, endoscopy clinics, and other departments.
Dental instruments and other items requiring high-precision cleaning.
The Yunyi YL series of laboratory ultrasonic cleaners includes low-frequency, high-frequency, dual-frequency, triple-frequency, and multi-frequency ultrasonic cleaning equipment options to meet various laboratory applications.
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, catering to different cleaning needs.
Features and Advantages
Excellent cleaning performance: Ultrasonic cleaners offer high cleaning efficiency and speed, particularly for blind holes and objects of various geometries, achieving cleaning results unmatched by other methods.
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, catering to different cleaning needs.
Intelligent control: The equipment is usually equipped with a PLC system and a color touchscreen, enabling real-time display and adjustment of cleaning parameters such as temperature, time, ultrasonic frequency, and power via password protection. It also features automatic water intake, drainage, circulating heating, ultrasonics, and automatic enzyme addition, achieving full automation.
Strong protection: To prevent instrument damage, hidden heating methods are used for automatic heating with adjustable temperature settings. Additionally, ultrasonic power can be adjusted in real-time via the touchscreen to suit different cleaning requirements.
Wide application: Triple-frequency ultrasonic cleaners are widely used in various industries such as surface coating, machinery, electronics, medical, and semiconductor sectors, capable of cleaning objects of diverse materials and shapes.
