This is achieved by controlling the ratio between the droplet transport time across the trifurcating junction and the drainage time of the fluid volume separating the droplets t r/t d. Three different microfluidic trifurcation geometries have been designed and compared for their droplet fusion efficiencies. Fusion of up to six droplets has been observed in these devices. The fusion of two droplets occurs when t r/t d is equal to 1.25 and the number of fused droplets increases with t r/t d. When the junction length (d) is 216μm fusion of 2-6 six droplets are possible however when the junction length is increased to 360μm fusion of only two droplets is observed.
