Injector Cleaning and Maintenance

Daily Maintenance:
STOP
Weekly/Periodical Maintenance:
2008-07
The required maintenance may vary with your application. The following
procedures are recommended for optimal performance and maximum life of the
injector system.
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.
Do not allow the pump(s) to run dry for more than a few cycles.
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.
ETHANOL IS FLAMMABLE AND WHEN IMPROPERLY HANDLED CAN
LEAD TO EXPLOSIONS. PROPER LABORATORY SAFETY
PRECAUTIONS MUST BE OBSERVED.
