Sample tray operation
At initialization, the tray rotates clockwise until STT position 1 is in the aspiration
position.
After you start a run, the sample tray moves clockwise to position 1, then it rotates
clockwise to move samples successively to the aspiration position.
If samples are identified by barcode, each sample detected by the barcode reader stops (in
turn) in the aspiration position. If samples are identified by position number, they move
by position number to the aspiration position. Regardless of the mode, you must enter
samples by a workorder, or they are not processed.
Monitor the progress of samples on the sample tray in the Test Result Monitor window.
If an assay is not running, you can operate the unit manually from the Manual Operation
window.
Container types
You place sample containers defined in the Order Entry window in the STT and CTT .
You can use 5-mL, 7-mL, or 10-mL collection tubes or 2-mL sample cups. You have to
put the small sample cups into plastic holders before you place them in the tray
positions..
The dead volume for the collection tubes is 200 µL, and the dead volume for the sample
cups is 50 µL.
You can use barcode labels on collection tubes but not on sample cups.
SMP Pause
Use the SMP Pause button at the Operation Panel to temporarily stop sampling so you
can add samples to or replace the STT/CTT tray.
