Abstract

Methods of controlling environmental conditions within a fluidic system e.g. preventing bubble formation, where such environmental conditions can affect the operation of the system in its desired function, and fluidic channels segments (102), devices and systems that are used in practicing these methods. Such environmental conditions are generally directed to the fluids (104,108 and 112) themselves, the movement of such fluids through these systems, and the interaction of these fluids with other components of the system e.g., other fluids or solid components of the system.
