Microfluidic technology, which offers capabilities for the precise handling of small fluid volumes dispersed as droplets is discussed. Simultaneous generation of multiple size droplets are required to fully exploit the potential. Two methods for passively breaking larger drops into precisely controlled daughter drops using pressure-driven flow in simple microfluidic configurations are demonstrated. The conditions for breakup at a T junction are quantified and sequential breakup at T junctions for making small drops at high dispersed phase volume fractions are illustrated.
