CHANNEL DESIGNS AND COMPONENTS

Fluidic modules configured for flowing fluid through membranes and associated methods are generally provided. In some embodiments, a fluidic module comprises two channels between which a membrane is positioned. The two channels may have geometries such that the pressure drop experienced by a fluid flowing from the first channel, through the membrane, and into the second channel is substantially independent of the location along the channel at which it flows through the membrane. In other words, the pressure drop may be substantially constant over the membrane area.
