There is not enough fluid in larger
chamber of ABC, or the anode buffer
has spilled into smaller overflow
chamber.
Pipette the buffer from the smaller
overflow chamber to the larger
chamber. Ensure that the buffer is
filled to within ±1 mm of the fill line.
When installing new ABC, tilt the
container to move buffer to the larger
side of the container as described in
“Install the anode buffer container
(ABC)“ on page 229.
When you remove the heat seal from
a new pouch, some residual seal

behind on the pouch cap.
Use a pipette tip to remove the entire
seal from the pouch cap before
installing on the instrument.
