<p>A sheath flow type flow-cell device for Flow-Cytometer comprises a first inlet (6) for sheath fluid, a flow passage (9) communicated with the first inlet and contracted toward downstream, the flow passage having a substantially rectangular cross section, a straight capillary flow passage (8) connected to the flow passage at downstream thereof, the capillary flow passage having a substantially rectangular cross section, a second inlet (7) for sample fluid, a nozzle (10) communicated with the second inlet and opened within the flow pasage in the same direction as the flow direction of the straight capillary flow passage, a discharge port (3) provided at a terminal end of the straight capillary flow passage, and flow regulating means (8a, 8b; 19; 20) for regulating the flow of the sheath fluid in the straight capillary flow passage to be a laminar flow having a gradient of flow velocity.</p> |
