Sheath-less flow for high throughput particle separation using integrated spiral. Experimental results of two integrated spiral. (A) Particle size with 10 and 15 μm introduced at the inlet, where 10 and 15 μm particles are pre-focused in the first spiral and follows to the next spiral, where the 15 μm particles remains at the inner wall, while the 10 μm particles moves towards the outer wall of the channel. (B) Separation of particle 10 and 15 μm at a high flow rate of 1 ml/min, indicating a separation efficiency of 89% for 10 µm particles at the outer outlet and 99% for 15 µm particles at the inner outlet.
