Backwash and Rinse
The Diluter performs backwash of aspiration pathways and rinses its components.
Approximately 0.5 mL of Erythrolyse II erythrocyte lytic reagent is delivered to the mixing
chamber to remove residual material from the previous cycle.
10 mL of diluent rinse for the WBC bath comes from the RBC diluent dispenser, and 6 mL of
diluent rinse for the RBC bath comes from the WBC diluent dispenser. The WBC bath needs a
larger rinse volume to:
r
Remove RBC cell stroma after lysing
r
Remove remaining lytic reagent
r
Rinse above the 7 mL fill line
r
Rinse the hemoglobin cuvette.
