Abstract
A sheath flow type flow-cell device for plow-cytometer which comprises a first inlet for sheath fluid, a flow passage communicated with the first inlet and contracted toward downstream, the flow passage having a substantially rectangular cross section, a straight capillary flow passage connected to the flow passage downstream thereof, the capillary flow passage having a substantially rectangular cross section, a second inlet for sample fluid, a nozzle communicating with the second inlet and opened within the flow passage in the same direction as the flow direction of the straight capillary flow passage, a discharge port provided at a terminal end of the straight capillary flow passage, and flow regulating means 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.
