Dilution Washer (DWUD)
Figure 1-24. Dilution tray wash mechanism
The DWUD has ten nozzles, each performing a stage of the wash. Each nozzle works on
a different cuvette, so the DWUD washes ten cuvettes simultaneously. The cuvettes are
being washed in different stages at the same time.
After a cuvette is washed by one nozzle, it moves to the next until washing is complete.
While the DTT rotates, the DWUD is in the up position.
