Fisher FS140 Ultrasonic Cleaner
Ultrasonic cleaners or ultrasonic baths are cleaning devices that transmit high-frequency sound waves through liquid to clean laboratory equipment. Cleaning occurs when the sound waves, typically 40 kHz, agitate water or a solvent-based liquid to cause cavitation or bubbling. The resulting molecular explosions create enough force to dislodge dirt or other contaminants from the surfaces of items immersed in the liquid. This process can also disrupt cells or other biological materials for sample preparation or can be used to remove dissolved gases in solvents, a process called degassing or defoaming.
