Fluorescence microscopy images (top: a–d) of the mixing zones in devices with 4 selected SHB designs A, B, C and D, with their corresponding simulation results (bottom: a’–d’). Rhodamine B conjugate 70 kDa dextran (red) and Fluorescein (green) are used for fluorescence visualization, with flow rates Q for each inlet of 6 µL·min−1 and Re ca. 20 in the repeated ring-shaped units.
