Abstract

This research presents an multi-stage multi-orifice flow fractionation (MS-MOFF) device designed for achieving high recovery and purity simultaneously. The structure and dimensions of the MS-MOFF were determined by the hy-drodynamic principles to have consistent Reynolds numbers (Re) at each multi-orifice segment. From this device, we achieved improved recovery and maximize purity by collecting and re-separating the non-selected particles. The final recovery increased from 73.2 % to 88.7 % while the purity slightly decreased from 91.4 % to 89.1 %. The MS-MOFF device can be utilized to isolate rare cells from human blood solely by using inertial microfluidic forces.
