Sort Block
After leaving the nozzle, particles pass through the sort block where they are
either transported to waste via the waste aspirator, or sorted into a collection
device in the sort collection chamber. The sort block houses the high-voltage
deflection plates, along with the aspirator and aspirator drawer (Figure 1-11).

Note that the entire sort block assembly can be rotated on a fixed pivot point to
adjust the position of the stream in the waste aspirator. If the keyed stream
position differs between an old nozzle and a new one, the stream might not hit
the center of the aspirator after the nozzle is changed. In this case, you can
change the angle of the sort block by loosening the adjustment screws on either
side of the deflection plates and rotating the sort block. Tighten the screws when
the stream is re-centered in the aspirator.
