Reagent tray operation

At initialization, the trays rotate clockwise until reagent bottle 1 is in the aspiration
position.
After you start a run, the reagent trays move clockwise to position 1, then they rotate
clockwise or counterclockwise (whichever results in a smaller rotation) to move reagents
to the aspiration position. The number of trays and reagents used depends on the
specified assay conditions.
To check the reagent volume and number of tests remaining in a container, use the
Reagent Inventory window.

Reagent container types

Place reagent containers defined at the Reagent Container Settings window in the reagent
trays. The trays can hold 20-mL, 40-mL, or 70-mL wedge-shaped containers.
At this window, you also specify the reagent type (R1 or R2) for each reagent container.
Barcode labels on reagent containers have the test name, expiration date, lot number, and
container ID number. You can initiate a barcode scan at the Reagent Inventory window.

RGT Pause button

Use the RGT Pause button to temporarily stop testing, on the analyzer or from a lab
automation system, so that reagents can be added or removed at the reagent trays.
NOTES
•
Do not
•
The text on the RGT Pause button is gray when inactive and black when active. After
the button is selected, the RGT Pause process can take some time. The system will
safely complete any tests on samples that have been aspirated.

Sample aspiration and dilution mechanisms

The sample-dilution probe (DPP) aspirates sample from the sample tray (STT), from a
laboratory automation system (LAS), or from the universal rack handler, and dispenses it
into cuvettes in the dilution tray (DTT), according to the specified assay conditions. The
dilution pumps handle the aspiration and dispensing functions.
Using these mechanisms, you dispense the following items into the DTT cuvettes:
•
sample diluted with standard diluent
•
sample diluted with special purpose diluent
•
undiluted sample
For more detailed information on how sampling is dispensed, refer to the online
Operator's Guide
