a recess having a non-uniform depth, the recess having a central portion and a peripheral portion, wherein the depth of the central portion is less than the depth of the peripheral portion,
a fluid inlet port and fluid bypass port, each in fluidic communication with the peripheral portion of the recess and located at a respective one of two opposing edges of the recess; and
b) a cover member configured to sealingly engage the first face of the filter housing, the cover member having a gas outlet port positioned at or near the center of the cover member,
the cover member having:
an inner face configured to support the membrane filter,
