Spiral sorter

Microfludic chip x1

Microfluidic generation of droplets can produce highly monodispersed droplets with high frequency (up to hundreds of kHz). Interest in droplet-based microfluidic systems has grown substantially, because microfluidics offers the ability to handle very small volumes (μl to fl) of fluids, provides better mixing, encapsulation, sorting, and sensing. Microfluidics can be used for high throughput experimentation. Microfluidic-based droplets have many diverse and varied applications such as particle synthesis and chemical analysis. Highly controlled droplet production also makes single cell analysis, or drug testing possible.

Spiral sorter, Fluidic 382, PMMA is made poly(methyl methacrylate). Spirals can be used to separate particles according to their size due to Dean forces. Channel dimension, number of spirals and diameter of the curvature influence the sorting effect. The sample is introduced through a central inlet and fractions with cells/particles of different size can be received at the different outlet ports.
