Abstract
Discrete microfluidics offers distinct advantages over continuous microfluidics since the need for flow presents significant problems. Here, we demonstrate a method of achieving the gentle transfer of liquid samples between two capillaries with the use of air actuation which limits flow and is amenable to automation. Since the stability of liquid bridges is in operation, there is a relationship established between the gap distance and the liquid volume, thereby resulting in three physical response types that were identified. Only one of these allows for efficient liquid transfer. We advance a model for the optimal gap distance and show that it is in good agreement with the experimental data. During the process of liquid transfer, favorable mixing is also achieved.
