8.3.1
Daily Maintenance:
If not otherwise stated by the manufacturer of the kit to be used, the following
tasks must be performed at least daily:
•
Inspect the pump(s) and tubing for leaks.
•
Flush the whole system thoroughly with distilled or deionized water after
each use and when the pump is not in use. Failure to do so can result in
crystallization of reagents. These crystals can damage the syringe seal and
valve plug resulting in leakage.
CAUTION
DO NOT ALLOW THE PUMP(S) TO RUN DRY
FOR MORE THAN A FEW CYCLES.
8.3.2
Weekly/Periodical Maintenance:
The injector system (tubing, syringes, injector needles) must be cleaned weekly
to remove precipitates and eliminate bacterial growth:
Follow these steps to clean the pump/injector system with 70 % EtOH (ethanol):
1.
Depending on the user’s application flush thoroughly the system with buffer
or distilled water before washing with 70 % EtOH.
2.
Prime the pump with 70 % EtOH with syringes fully lowered for 30 minutes.
3.
After the 30-minute period, cycle all the fluid from the syringe and tubing into
a waste container.
4.
Wash the pump/injector system with 70 % EtOH
5.
Wash the pump/injector system with distilled or deionized water
6.
Prime the pump/injector system with distilled water. Leave the fluid pathway
filled for storage.
7.
Clean the end of the injector needles with a cotton swab soaked in 70 %
ethanol or isopropanol.
WARNING
RISK OF FIRE AND EXPLOSION!
ETHANOL IS FLAMMABLE AND WHEN IMPROPERLY HANDLED
CAN LEAD TO EXPLOSIONS. PROPER LABORATORY SAFETY
PRECAUTIONS MUST BE OBSERVED.
