Abstract
According to various aspects, a flow system for transporting microparticulate samples in a hydrodynamically planar flow in a selected flow direction includes a flow chamber extending in the flow direction, having first and second apertures on opposed surfaces of the flow chamber. A sheath-fluid channel has first and second branches to carry the sheath fluid into the flow chamber through the first aperture and having orientations separated by less than about 15° at the first aperture; and third and fourth branches to carry the sheath fluid through the second aperture and having orientations separated by less than about 15° at the second aperture. In some examples, guide channels extend from the apertures substantially perpendicular to the flow chamber at the apertures, and sheath-fluid channel supply sheath fluid to the guide channels. Flow systems can be used in image flow cytometers for observing microparticulate samples, e.g., using scanning irradiation.
