From: A centrifugal microfluidic cross-flow filtration platform to separate serum from whole blood for the detection of amphiphilic biomarkers

Schematics of one-step (A) vs. two-step (B) cross-flow filtration, with corresponding photos of phase separations on the microfluidic device; (A) the one-step filtration method was ineffective at separating a large fraction of blood cells from serum; (B) the two-step filtration method was successful at separating serum from blood.
