Dilution tray wash mechanisms

The dilution washer (DWUD) washes dilution tray (DTT) cuvettes after sample analysis is complete, so they can be reused.

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.
