We present herein a microfluidic system based on passive effects for continuously separate a diphasic fluid-particles flow. Initially developed as a portable blood fragmentation device, its ability to operate passively, on several kinds of objects – organic or inorganic – opens the way to environmental applications, such as water cleaning or analysis. This technology can be implemented as a SamplePrep system, first step of an on-site analysis protocol. In addition, its low-cost and reliable manufacturing, compact size, low weight and ease of use make this technology a possible support for the deployment of health policies in developing countries.
