FIG. 6.

Yeast cell fractionation in 0.05× EMG 408 ferrofluid at various flow rates of the cell suspension: (a) Superimposed images of four groups of yeast cells at the expansion of the main branch; (b) Experimentally measured (symbols with error bars to cover the span of the cell stream) positions of each cell group at the expansion of the main branch. The flow rate ratio between the sheath fluid and yeast cell suspension is fixed at 20. The upright arrow In the right-most image of (a) indicates the reference point to which the position of each group of cells in (b) was measured.
