• Needs instrumentation including micro-dispensing valves, control boxes (spike/hold), pressure reservoirs, and microscopy for flow observation.
• Demands cross-team standardization of droplet volume calibration, nozzle positioning, and reservoir setup to ensure consistent performance.
• Involves adaptation considerations for different channel geometries, fluid viscosities, and droplet angles to avoid inlet overflow or unstable flow shells.
• Includes practical limitations such as bubble formation risk if pressure head is unstable, and the need to manage outlet drop size to prevent backflow or inlet perturbation.
