WebThe concept of a circular economy involves designing products and systems to minimize waste and maximize the use of resources, to create a closed-loop system in which waste is eliminated or repurposed into new products. WebUsing this system, it is possible to perform an injection of a sample plug into a circular micro-channel and then drive the sample through the channel, using shear flow induced by a rotation stage. High pumping rates at uniform speeds are attainable with this system with very little heat production.
