Brand: Roche

Model: cobas s 201 system

Type: User manual

Roche cobas s 201 system is a fully-automated sample preparation and pipetting system designed for use with the cobas 8000 modular analyzer series. It offers precise and accurate liquid handling for a wide range of applications, including clinical chemistry, immunochemistry, and molecular diagnostics. The system features eight pipetting channels, each capable of handling volumes from 1 to 500 µL. It also includes a barcode scanner for sample and reagent identification, a centrifuge for sample preparation, and a heated deck for temperature-sensitive assays.

In addition to the PDM software applications previously described in this

manual certain PDM Pooling Manager functions are restricted to users

assigned a LABADMIN role.

Pooling Manager Trace Messages

The Hamilton Microlab STAR IVD / STARlet IVD Pipettor communicates

with the Roche PDM software to log every action that is carried out

during the pipetting process. These log messages can be viewed by the

laboratory administrator and used to help troubleshoot pipetting errors

1 Click the Pooling button in the global command button area in

other PDM applications to start the Roche PDM Pooling Manager.

5 Double-click the results to display the Roche PDM - Trace Results dialog

box (Figure 3.3).

The Trace Results dialog box displays pipettor status information at the

time the error occurred. This information includes the main and slave

errors, aspirate or dispense volume, and deck position for each of the eight

pipetting channels.

The Trace Results dialog box also displays the reason for the error.

The type of information that is displayed depends on the pipetting

step.

Use the up and down arrows to page through trace results for

adjacent pipetting steps.
