3500xL Genetic Analyzer 24-Capillary Array, 36 cm - FAQs

If the array is stuck in the pump, even after loosening the knob, squirt around the edge of the array head with distilled water and try to remove it again. If the array will not move, a service call may be required. Do not use excessive force or tools to try and remove it.

Some of the other causes of an Unstable Electrophoresis current detected error message are:

1.Leak on the system
2. Polymer that:
-Has expired
-Has been left on the instrument for more than the recommended time
-Is a mixture of expired polymer and non-expired polymer
3. Running Buffer that was:
-On the instrument longer than 2 weeks
-Not filled to the fill line or evaporated below the fill line
4. An arcing event that was not cleaned afterwards using the water wash wizard
5. Not performing regular maintenance on the instrument
6. Hardware issues

Inspect the system for leaks. If you do not see any leaks on the system, perform the wash the pump chamber and channels wizard using the conditioning pouch and place fresh, non-expired polymer and fresh Anode and Cathode buffer containers. If the problem persists, a service call may be required.

The Applied Biosystems 3500/3500xl Genetic Analyzer capillary arrays are warrantied for a specific number of runs or until the expiration date printed on the array package, whichever comes first. If you notice that you are starting to get reduced data quality (e.g., shorter reads, trailing peaks in all 4 colors) even with the Sequencing Standard, these may be signs that the array requires changing.

Thermo Fisher Scientific can only provide warranty on performance on non-expired reagents. Using reagents past their expiration date is a risk and may compromise your data integrity.

If the instrument is not in use, it is not necessary to replace the buffer every 14 days. However, the buffer level needs to remain at the fill line to prevent the capillary or array from drying out. Top off the buffer volume with water if necessary. Replace the anode and cathode buffer containers prior to starting a new run.
