A typical modern laboratory of today is filled with a number of high tech and advanced laboratory that have made the experiments and studies execution quite easier and more accurate than ever. Laboratory sonicators are one of those tools that have been evolved as a result of advance technology availability for making laboratory equipment. In this article, we will discuss how laboratory sonicators function, what mechanism underlies its functioning and the ways it is serving a number of industrial applications.
Sonication is the process of applying sound energy in order to agitate or shake particles in the sample, for different purposes. Ultrasonic frequencies are generally used, that leads to the mechanism of the process being used, called ultra-sonication. In a laboratory, it is generally applied through ultrasonic probe or ultrasonic bath, colloquially termed as laboratory sonicator. An ultrasonic foil in a paper machine can spread cellulose fibers with more uniformity and can strengthen the paper.
Sonicators have various effects, both physical and chemical. The chemicals effects are related to understanding of the impact of sound waves on the chemical systems to which it is being applied. This is called sonochemistry when the chemical impacts of ultrasound don’t arise as a result of direct contact of molecular species. As per recent studies, it has been revealed that no direct coupling of acoustic field with the chemical species on molecular level is the basis of sonochemistry. Instead, it arises from the acoustic cavitation, including growth, formation and implosive bubble collapse in the liquid.
Laboratory sonicators are used for the formation of nano particles as well, like nanocrystals, nanoemulsions, wax emulsions and liposomes, and for purification of waste water purification, extraction of plant oil, degassing, extraction of anthocyanins and antioxidants, crude oil desulphurization, production of biofuels, adhesive thinning, epoxy processing and a number of processes.
