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 physical "cavitation effect" of ultrasonic waves propagating through the cleaning liquid medium. The ultrasonic generator produces high-power electrical energy at ultrasonic frequencies above 20 kHz, 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 penetrate into the tiny gaps and grooves on the surface of objects, dislodging dirt and impurities from the object's surface.
Ultrasonic frequencies suitable for laboratories include conventional mid-to-low frequencies such as 28 kHz and 40 kHz, as well as high frequencies: 60 kHz, 80 kHz, 120 kHz, 200 kHz, etc. Yunyi Laboratory Ultrasonic Cleaner Series (multiple frequency options: 28, 40, 68, 80, 120, 132, 175, 200 kHz).
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.
Commonly used laboratory glassware such as test tubes, beakers, etc.
Surgical instruments, endoscopes, and other equipment in hospital operating rooms, endoscopy clinics, and other departments.
Dental instruments and other items requiring high-precision cleaning.
Laboratory ultrasonic cleaners, Yunyi YL Series, include 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., 40 kHz, 80 kHz, 120 kHz), which can be combined in various ways to achieve single-frequency, dual-frequency, or triple-frequency cleaning modes, catering to different cleaning needs.
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.
