Abstract:
A device comprising:a housing comprising a lid, a base substantially parallel to the lid, and a fluid access port in the lid; a fluid permeable filter within the housing comprising a region for fluid access fluidly connected to the fluid access port, and a region for fluid egress, wherein the filter comprises a substantially smaller depth dimension in comparison to its length and width dimensions, wherein the length/width plane of the filter is oriented within the housing substantially parallel to the lid and base, and wherein said filter is compressed in one specific region, but not in all regions of said filter, whereby fluid and particulate matter flow in said compressed region is retarded; a fluid flow path through the filter that is a lateral flow path from the region for fluid access through the filter to the region for fluid egress; and a fluid egress port in the base or between the lid and base comprising a capillary space fluidly connected to the region of fluid egress from the filter, wherein fluid flows from said filter to said capillary space.
