Why is my Applied Biosystems 3500 polymer delivery pump so noisy?
- M
  Michael MosleyJul 28, 2025
  The polymer delivery pump (PDP) may be excessively noisy due to a couple of reasons. First, the array locking lever might not be in the correct position. Ensure it is locked correctly; if not, contact Thermo Fisher Scientific. Second, the polymer delivery pump block may not be pushed back into position after a capillary array change. Gently push the buffer-pin valve lever (yoke). If it doesn't move freely, restart the instrument and computer. If, after restarting, the lever still doesn't move freely, contact Thermo Fisher Scientific. Otherwise, push the upper polymer block all the way back against the wall.

What to do if Applied Biosystems 3500 autosampler doesn't move the plate?
- R
  Rick YoungAug 5, 2025
  If the autosampler isn't moving the plate, several factors could be at play. First, check that the plate retainer, plate (or tube strip), and plate base are assembled correctly, listening for a snap when clipping them together. If array tips are bent, replace the array. Also, ensure the plate base sits flat on the autosampler, with the pins aligned with the holes at the bottom and the sides latched. Securely clip the plate retainer and plate base together if the array lifts the retainer off the base. Finally, make sure the septum is fully inserted into position, listening for a click.

What does blinking amber light mean on Applied Biosystems 3500?

  Louis MendozaAug 19, 2025
  A blinking amber light on the front panel indicator of your Applied Biosystems Measuring Instruments means either the run is paused (resume run), or the instrument door is open (close the instrument door).
