Storage
•
The QualAssure Kit should be stored at room temperature (15 °C to 25 °C).
•
Kits should be stored in the dark to the extent practical.
• If the solutions freeze, they should be allowed to equilibrate at room temperature for several hours
(or overnight), mix gently by inversion at least 20 times, and check for precipitate.
If no precipitate is visible, the solutions can be used without limitation for the specified shelf life.
If precipitate remains, repeat mixing.
Using PCS QualAssure solutions
•
Transfer an amount of QualAssure to the aliquot container that will be used within 30 minutes. Pipette
samples from the aliquot container.
•
Dispose of any unused solution. Do not return unused solution from the aliquot container
to QualAssure bottles.
•
Always keep QualAssure bottles and aliquot containers tightly capped when not in use.
•
Do not pipette samples directly out of the QualAssure bottles.
•
PCS2/PCS3 users will need to ensure all QualAssure solutions and vials belong to the same Lot Code.
PCS Calibrator Kit
•
Components of the PCS Calibrator Kit should not be exposed to light. For PCS instruments, keep
the vials in the box until ready to use. For PCS2/PCS3 instruments, the calibrator vials are protected
from light during equilibration in the vial block holder.
•
PCS2/PCS3 instruments do not have an integrated infrared temperature sensor and require all PCS vials
to be equilibrated within the vial block for 15 minutes before use.
•
If the QualAssure solutions have been moved from another location, additional equilibration time in the
vial block may be required.
Disposal
•
Dispose of PCS QualAssure solutions in accordance with local, state, and federal regulations.
Vial Cleaning
To ensure accurate results, all vials should be free of fingerprints and smudges
prior to use.
• To clean the vials, hold by the cap and gently wipe the lower portion of the
vial by rotating the vial against a lint-free wipe.
• If there are visible smudges on the vial use HPLC-grade isopropyl alcohol on
the lint-free wipe to remove them.
