Developing and exploiting applications of functional nanomaterials often require colloidal nanoparticles with defined properties. Their production suffers from batch-to-batch variability as well as poor shelf life, and distributors demand high prices. The conditions for innovative application research must be improved by easier and more robust access to colloidal nanoparticles. A compact and fully automatic benchtop machine has been developed for quick, easy and reliable production of colloidal nanoparticles. The machine uses the method of laser synthesis of colloids, converting almost any solid of choice into colloidal nanoparticles. In addition, different dispersants and stabilizers can be dosed, if desired. An almost infinite range of colloids becomes available with one machine. We provide an insight into the operation of the machine and report in particular on the high performance efficiency of the laser-based synthesis. Furthermore, we highlight the benefits of using the device in R&D of colloidal nanoparticles made possible by the technology.
