The present invention is generally directed to methods, apparatus and systems for use in performing in situ dilution or concentration of a particular subject material in a microfluidic device or system. These methods and apparatus may generally be integrated with other microfluidic operations and/or systems, to perform a number of different manipulations, wherein dilution or concentration, carried out within the context of the microfluidic device or system, is just one part.
