Place a clean Cedex Sample Cup in the DefaultCup position on the Multi Sample Tray or attach it to the
sample port, for a system with a single sample port.
Perform a Prime (see “The Hardware Management Dialog Box”).
In the case of a system with a single sample port, ensure that a Cedex Sample Cup is always attached
to the single sample port. The Cedex Sample Cup (4 mL) is correctly attached when it is in an upright
position beneath the sample port, and the capillary tube almost reaches the bottom of the Cedex Sample
Cup:

4.2 Refilling Containers Individually
To ensure optimal performance, the reagents must be free of impurities such as dust, crystals, biological material,
or fluff. The Roche Cedex HiRes Reagent Kit guarantees optimal handling with the best possible safety. One
Reagent Kit pack is sufficient for approximately 100 measurements, including the standard cleaning routines.
Reagents can be refilled, or emptied in the case of waste, on an individual basis.
If you are using your own reagents, it may be necessary to filter them before use. Roche Diagnostics
recommends using the Cedex HiRes Reagent Kit.
1
Thoroughly clean each Reagent Kit container before refilling to avoid impurities such as dust and fluff or
contamination with microorganisms, to ensure optimal functioning of the Analyzer.
2
Fill the Detergent container to the required level with Cedex Detergent (see label).
Only Cedex Detergent should be used for the cleaning procedures in order to prevent damage to the
sensitive surface of the Liquid Management components.
3
Fill the Cleaning Solution container to the required level with Cedex Cleaning Solution (see label).
4
Fill the Water container to the required level with distilled or deionized water (see label).
5
Fill the Trypan Blue container with 0.2% Cedex Trypan Blue solution to the required level (see label).
Use only 0.2% Cedex Trypan Blue Solution. If necessary, dilute a more concentrated Trypan Blue solution
with buffer (Phosphate Buffered Saline (PBS), pH 7.4).
6
Place all of the reagent containers, as well as the emptied waste container, in the appropriate positions in the
Reagent Tray.
Confirm each change individually by clicking on the respective SET FULL button or EMPTY button, in the
case of waste, in the Reagent Kit Status dialog box.
7
Place a clean Cedex Sample Cup in the DefaultCup position on the Multi Sample Tray or attach it to the
single sample port and perform a Prime (see “The Hardware Management Dialog Box”).
