  • Patent number: 8189187
    Abstract: An improved optical flow cell adapted for use in a flow cytometer for differentiating formed bodies (e.g., blood cells). Manufactured from a monolithic transparent material, the improved flow cell has an internal flow channel of polygonal transverse cross-section through which prepared samples can be metered and an external envelope suited to acquisition of optical parameters from formed bodies in such samples. Preferably, such flow cell is formed by a glass-drawing process in which a relatively large glass preform having a rectilinear internal channel of a desired polygonal cross-sectional shape is heated and drawn to achieve a desired cross-sectional area of reduced size. Also disclosed are preferred methods for differentiating formed bodies using the flow cell of the invention.
    Type: Grant
