At initialization, the SPP moves (in the up position) to the RRV cuvette, then stops above the wash port. The pumps stop when the SPP is positioned over the RRV cuvettes.
Each sampling cycle consists of these steps:
The SPP moves to the aspiration position of the DTT and aspirates the sample.
The SPP moves back to the wash port, where deionized water washes the SPP’s outside surface.
The SPP moves to the RRV and dispenses the sample into a cuvette.
The SPP returns to the wash port, where degassed water washes the inside and outside of the SPP.
The SPP is now ready for another cycle.
If an assay is not running, you can operate the unit manually from the Manual Operation window.
