Fluidics Components
When the fluidics system is activated, the sheath fluid from the pressurized sheath
tank is forced from the fluidics cart up into the cuvette flow cell where
hydrodynamic focusing forces particles from the sample injection chamber
through the cuvette in a single-file stream.
Within the cuvette flow cell, laser light is focused on the sample core stream.
Fluorescent molecules excited by the different laser wavelengths are detected by
the optics and analyzed by the electronics. Particles are then either transported to
waste reservoirs via the waste aspirator, or sorted into a collection device within
the sort collection chamber.
The following fluidics components are described in this section. See Figure 1-7 on
page 24. For more information about fluidics, see Fluid Movement on page 44.

The flow cell access door is equipped with a shutter mechanism that shuts
off the laser light when the door is opened. To ensure there is no interruption
to data acquisition, do not open the door while sorting or recording.
