Reagent Trays; Reagent Tray Operation - Siemens ADVIA 1800 Operator's Manual

Reagent trays

Reagent trays 1 and 2 (RTT1 and RTT2) contain reagents used for assays (positions
1 - 52) and the detergents used for daily washing and contamination prevention (positions
53 - 56). The reagent probes (RPP1 and RPP2) aspirate the required reagent and dispense
it into reaction tray (RRV) cuvettes for analysis.
Figure 1-11. Reagent probes
Each tray has 56 positions. RTT1 contains the first reagent (R1); RTT2 contains the
second reagent (R2).
You can use any reagent container for more than one test item; a test item may require
more than one reagent container.
Each reagent tray has a barcode reader (RBC-1 and RBC-2).

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.
