Maintenance Procedures
QIAgility User Manual 11/2011 8-3
Note : Do not wipe the rails. These rails support the pipetting
head and allow it to slide backwards and forwards easily.
Wiping the rails will remove the grease and make them more
susceptible to rust.
8.2 Periodic maintenance
8.2.1 Decontaminating the QIAgility
To remove DNA/RNA from the worktable and to eliminate
cross-contamination, the QIAgility must be routinely
decontaminated. Proceed as follows:

the worktable. Wash these in detergent and rinse with
clean water.
2. Soak these components in TriGene (Medichem
International; for more information, see www.medi-
mark.co.uk), or one of the tested cleaning agents listed
in Section 8.1.1 above, for 15–30 min.
3. Thoroughly rinse the components in nucleic acid-free
water.
4. Briefly rinse with absolute ethanol and dry with a soft
paper towel.
5. Spray the instrument worktable with TriGene, or one of
the tested worktable cleaning agents listed above, and
allow to stand for 15–30 min. Wipe away with clean
paper towels.
6. Spray the worktable the nucleic acid-free water and dry
with clean paper towels. Repeat this 3 times.
7. Spray the worktable with TriGene, or one of the tested
worktable cleaning agents listed above, and allow to air
dry.
8. Return all components to the worktable and close the
hood.
