Flow Cells
NOTICE
Flow cells are sensitive to dirt and dust. Observe the following notes
when handling flow cells:
•
Mechanical shocks, mechanical vibrations or intruding objects can
lead to leaks on the flow cell or even destroy it. Avoid exposure of
the flow cell to mechanical shocks or vibrations. Do not let it hit hard
surfaces. Do not intrude the flow cell enclosure with any objects.
•
The optical ports of the flow cell are sensitive to contamination and
scratches. Do not immerse the optical ports of the flow cell.
•
On the rear side of the flow cell, the contact pads for the
identification chip are located. Never touch the contact pads. Avoid
damage to the electronics of the ID chip.
•
Particulate matter, dust and debris can lead to contamination and
clogging of the flow cell. If capillaries are removed from the flow cell
inlet and outlet, install protective plugs to close the ports and to
prevent particles from clogging the flow cell in the next application.
Always use the plugs that were installed when the flow cell was
shipped.
