The Flow Cell Assembly contains the fluidics and hardware needed to
hydrodynamically focus the RBC/PLT and WBC sample streams in the path of the
laser beam for analysis. The primary components of this assembly are:
• Sample Feed Nozzle — a specially designed tube used to deliver the diluted
sample into the sheath stream
• Sample Flow Cell — an optically clear quartz chamber with a central square
opening of a specific size, which flares out into a cone at the bottom of the
flow cell
The Laser Optics Bench Assembly (located behind the Flow Panel) contains the
Helium-Neon laser, the flow cell, and the optics and detectors required for
enumeration and differentiation of white blood cells, red blood cells, and platelets
(refer to Figure 1.10).
CAUTION –
CLASS 3B LASER LIGHT WHEN OPEN.
AVOID EXPOSURE TO BEAM.
