Abstract
Some configurations of a microfluidic apparatus can comprise a fluidic circuit of interconnected fluidic structures into which a plurality of different media can be introduced or extracted. A variety of operations can be performed with the different media including isolating with a second medium one or more of the fluidic structures that is filled partially or fully with a first medium. Discrete volumes of a medium can be moved through the isolating second medium to deliver materials or micro-objects to or remove micro-objects or materials from a fluidic structure that is otherwise isolated by the second medium. Some configurations of a microfluidic apparatus can isolate microfluidic structures in a microfluidic apparatus using flow rates or blocking structures, and some configurations can manage bubbles in fluidic structures.
