7.6 Cleaning and testing the reagent
cartridge
If the reagent cartridge is to be reused, it must be cleaned
directly after use. It is recommended that the reagent
cartridge is used a maximum of 20 times.
WARNING Sharp needles
[W7]
Do not touch the sharp needles at the bottom of the
reagent cartridge. Handle the needles with care. Small
particles and fibers may obstruct the needles.
Note : Be sure to observe all federal, state, and local
environmental regulations for the disposal of laboratory
waste.
The following items are required:

Powder-free gloves

High-purity water (Milli-Q 18.2 MΩ x cm or equivalent)

Clean, lint-free cloths
There are two possible cleaning procedures: A standard
cleaning procedure (Section 7.6.1) and a cleaning procedure
for clogged cartridges (Section 7.6.2). Ensure that a cleaned
cartridge is usable by performing a cartridge function check
(Section 7.6.3).
7.6.1 Standard cleaning procedure
Procedure:
1.
Discard any remaining solutions.
2. Rinse the cartridge four times with high-purity water.
3. Spray the outside of the needles with high-purity water.
4. Fill the compartments to the top with high-purity water.
Hold the cartridge over a sink or beaker while pressing
firmly on top of each compartment with a finger (wear
powder-free gloves). A jet of water should come straight
out of the tip of the needle.
5. If a needle is blocked, wet the needle tip with a drop of
high-purity water.
