25 KHz - The most powerful frequency to remove strong pollution. Do NOT use on mirror polish surfaces and sensitive materials like glass, aluminum， but the car parts is suitable for 28khz ultrasonic cleaning machine.
40 KHz - Standard frequency which can be compatible on a wide range of material and for removing a lot of pollution.
80 kHz - This frequency is used to clean parts with complex geometry. Cavitation bubbles can go into small holes to remove the pollution.
120 kHz - Main application in precision optics to clean very sensitive parts like wafers. The power of cavitation is low so these frequencies are used on clean parts to remove dust in final cleaning.
(80 kHz and above are only available on special request orders)
