12.6.2 CLEANING OF THE PIPETTOR NEEDLES
The inner and outer surface cleaning of the sample pipettor is aimed at preventing
sample build-up and thus carryover over time. Subsequent washing with system liquid
should remove all residual cleaning fluid so that future test orders are not compromised.
WARNING
Bleach MUST NOT be used as replacement solution due to the
high risk of residue remaining in the pipettor needle prior to test
processing.
NOTICE
As the pipettor maintenance is also performed partially by
the MosaiQ 125 for 15 minutes, you can meanwhile do other
maintenance tasks that are safe when the MosaiQ125 is connected
to the mains power supply. For example, on the external parts
and inside the drawers (solid and liquid waste, system liquid and
reagent drawer).
NOTICE
On completion of the cleaning, the remaining NaOH should
be discarded as per local guidelines. This reagent should NOT
be poured into MosaiQ liquid waste as it may react with other
components of the liquid waste.
This task performs an intensive cleaning of the pipettor needles.
To perform the cleaning:
1 - Fill a sample tube with a small volume (≥5mL) 0.5 M NaOH (Sodium Hydroxide) and
place it in position number 1 on a MosaiQ rack.
