Abstract
System configured to conduct designated reactions for biological or chemical analysis. The system includes a liquid-exchange assembly comprising an assay reservoir for holding a first liquid, a receiving cavity for holding a second liquid that is immiscible with respect to the first liquid, and an exchange port fluidically connecting the assay reservoir and the receiving cavity. The system also includes a pressure activator that is operably coupled to the assay reservoir of the liquid-exchange assembly. The pressure activator is configured to repeatedly exchange the first and second liquids by (a) flowing a designated volume of the first liquid through the exchange port into the receiving cavity and (b) flowing a designated volume of the second liquid through the exchange port into the assay reservoir. The system also includes a fluidic system that is in flow communication with the liquid-exchange assembly.
