Ultrasonic cleaners use sounds waves between 20 and 400 kHz to clean objects. An industrial ultrasonic cleaner usually relies on cavitations caused by the ultrasonic waves to perform the cleaning. Solvents with lower surface tensions will produce greater cleaning action. Choose a solvent your contaminants are soluble in. A higher frequency ultrasonic cleaner is generally capable of cleaning with greater detail and a bit more gently. A low frequency ultrasonic cleaner is generally considered a coarse instrument. We have a variety of ultrasonic cleaners ideal for your samples. Typical samples processed by ultrasonic cleaners include hard metals, ceramics, glass, and plastic.
