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.
Place reagent containers defined in the Reagent Container Settings window in the reagent trays. The trays can hold 20, 40, or 70-mL wedge-shaped containers.
On 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 on the Reagent Inventory window.
