Sample probe

Figure 1-20. Sample probe
After aspiration, the SPP is lowered into an RRV cuvette, where it dispenses the sample.
The tip of the probe is 2 mm deep into the solution, ensuring that no droplets remains on
the tip after withdrawal.
NOTE : Unlike the sample-dilution (DPP) and the reagent probes (RPP1 and RPP2), the
SPP does not have liquid level sensing. This is because the software is able to calculate
the volume of liquid in a DTT cuvette.

Analysis

Reaction tray

Figure 1-21. Reaction tray
For each sample assay, the reagent probes (RPP1 and RPP2) dispense reagent into
cuvettes in the reaction tray (RRV). Then the sample probe (SPP) dispenses diluted
sample into the cuvettes. To produce the reaction, reaction mixers (MIXR1 and MIXR2)
stir the mixture.
