A microflow device for separating or isolating cells from a bodily fluid or other liquid sample uses a flow path where straight-line flow is interrupted by a pattern of transverse posts which are arranged across the width of a collection region in an irregular or set random pattern so as to disrupt streamlined flow. Sequestering agents, such as Abs, are attached to all surfaces in the collection region via a hydrophilic permeable hydrogel coating. The collection region is formed as a cavity in a body molded from PDMS, which flexible body is sandwiched between a glass slide or comparable flat plate and a rigid top cap plate, both of which are pressed into abutting relation with the PDMS body by a heat-shrunk polymeric sleeve. Following cell separation and washing, cells can be released from the sequestering agents and the device centrifuged to force said cells to collect adjacent the hydrogel-coated slide or plate. Slitting the polymeric sleeve allows the body to then be peeled from the slide or plate, using an integral tab, to expose the separated cells on the top surface thereof for ready microscopic examination.
