We prevent your microstructures
With ultrasonic (<400 kHz), particles of up to 4 µm can be removed. For smaller particles down the nano-range, Megasonic (700 kHz up to 5 MHz) is neccessary.
In comparison to the conventional ultrasonic methods with e. g. 40 kHz the cavitation energy is substantially lower with the Megasonic system and it’s relatively high ultrasonic frequency of 1 MHz. The micro structures are therefore not destroyed.
