uFluidix - Micro-Mixing Device

The laminar nature of flow in microfluidic channels means the dominant mixing force is diffusion. This is more pronounced in smaller micro-channels of lets say smaller than 25um. Mixing two different reagents in micro-channels could be very challenging, especially in the case of immiscible liquids such as water and oil, or different viscosity of liquid — syrup and water. If mixing is needed, then one may choose a micro-mixer microfluidic device. Micro-mixers work by creating local turbulent flow, there are many designs and geometries, but the two most famous devices are serpentine mixers and herringbone mixers.
