2.5 Preparing the Reagent Kit
To ensure optimal performance, the reagents must be free of impurities such as dust, crystals, biological
material or fl uff. The Roche Diagnostics GmbH Cedex HiRes Reagent Kit guarantees optimal handling with the
best possible safety. One Reagent Kit pack is suffi cient for 100 measurements, including the standard cleaning
routines.
2.5.1. Installing or Changing the Reagent Kit
Proceed as follows to install or change the Reagent Kit:
1
Perform an LM Shutdown if the Liquid Management system has been primed (see “Carrying out an LM
Shutdown and HW Shutdown
”).
2
Open the Reagent Kit chamber in Cedex HiRes Analyzer by pushing the front upwards until it clicks into
place (see Figure 38, below).
3
Remove the old Reagent Kit with the tray and dispose of the old reagent bottles if necessary.
4
Open the new Reagent Kit and remove the covers from the individual containers.
5
Place the Reagent Kit containers in the appropriate positions in the reagent tray
(see Figure 38, below).
6
Close the front cover by pulling it all the way down. When the front cover is closed, the capillaries are
automatically correctly positioned in the individual containers.
7
Select the Reagent Kit Status option in the Functions menu of the Cedex HiRes Control Center. The
Reagent Kit Status window will open.
8
Click on the Replace all containers button in right-hand corner of the Reagent Kit Status window to
confi rm the changing of the Reagent Kit (see Figure 39). The Reagent Control display at the bottom right-
hand corner of the Cedex Control Center will turn from red to green and indicate the number of runs left.

Attach a clean Cedex Sample Cup to the sample port or place it in the DefaultCup position on the Multi
Sample tray and perform a Prime (see “
The Multi Sampler DefaultCup”).
