Performance tests of droplet volume consistency and temperature uniformity of the DMF cartridge. (a) Consistent volume of droplets generated on different droplet tracks from their corresponding reservoirs (n = 3 for each track/reservoir). (b) Infrared thermal imaging of a DMF cartridge filled with hexadecane providing uniform temperature distribution in two temperature zones for qPCR amplification. (c) Direct thermocouple measurements of hexadecane at locations 1–10 shown in (b) cross droplet tracks in 95 °C and 60 °C temperature zones (n = 3 for each location).
