Figure 39: Confi rming change of the Reagent Kit
For reliable functioning of the reagent control (correct number of possible measurements, or reporting an
impending overfl ow of the waste container), it is critical that all of the reagent containers are correctly fi lled
to the line with the appropriate liquid or, in the case of the waste container, completely emptied (see “Refi lling
Containers Individually ”). The changing of the reagents must then be confi rmed in the software as soon as
the Reagent Tray has been put back into the chamber. Failure to do all of the above will result in a mismatch
between the calculated reagents available as shown in the Reagent Control and the actual reagent amounts
in the containers or space available in the waste container.
The reagent control function that monitors reagent and waste levels can be turned off. See “Disabling the
Reagent Control”, for more information.
2.5.2. Refi lling Containers Individually
In order to ensure optimal functioning of the analyzer, each Reagent Kit container must be thoroughly cleaned
before refi lling. Impurities such as dust and fl uff or contamination with micro-organisms may thus be avoided.
Reagents can be refi lled, or emptied in the case of waste, on an individual basis. Each change can be individually
confi rmed by clicking on the respective Set Full button or Empty button, in the case of waste, in the Reagent
Kit Status window (see Figure 39).
If you are using your own reagents, it may be necessary to fi lter them before use. Roche Diagnostics GmbH
recommends using the Cedex HiRes Reagent Kit.
