A sonicator is a laboratory device that uses high-frequency sound waves, typically in the ultrasonic range, to agitate particles in a sample. This agitation can help in processes like mixing, emulsifying, or breaking down materials, making it useful in various fields such as chemistry, biology, and materials science. The device often consists of a transducer that converts electrical energy into ultrasonic waves, which are then transmitted through a liquid medium. Applications of sonicators include cell lysis, DNA extraction, and the preparation of nanoparticles, among others, enhancing the efficiency of these processes.
