On Board Dilution
On Board Dilution allows all samples for the UDR to be diluted prior to analysis. An aliquot of diluent
is placed into a cuvette. Then the Sample is dispensed into the diluent and mixed. On the next cycle,
the diluted sample is aspirated from the first cuvette and dispensed into another cuvette containing
the reagent. The diluent can be either a cartridge of DIL1 (PN 467826) or Component A in the UDR
cartridge.
