The Spinning Disc Reactor (SDR) is a method that provides rapid processing. This can be used for extracting oil from hemp, producing silver nanoparticles, and other hi-tech applications. While water cavitation is the primary use, this system can also be used for oil-to-oil botanical extraction. The system can also be used for experimenting with nano-emulsions. This systems allows you to develop and show cavitation and mixing science.
