A novel electrowetting-on-dielectrics (EWOD) device in open planar geometry allows probing of droplet mixing on a super-hydrophobic substrate under quasi contact-free conditions. We demonstrate a droplet-based microreactor with integrated convective-flow mixing for the reactive-mixing of CaCl2/Na2CO3 solutions. The device provides unique conditions for scattering, spectroscopy and imaging probes requiring an unobstructed droplet-access.
