(2) Washing of Flow Cell
(a) Wash the flow cell in running water.
If the contamination cannot be removed with running
water, then use an ultrasonic cleaner. In this case be
sure to put the flow cell in a paper or plastic container
and then place it in the ultrasonic cleaner, so as to
avoid scratching the cell.
(b) Wipe the surface of the flow cell with gauze that is
moistened with acetone or ethanol.
NOTE: Be careful not to scratch the flow cell surface when
disassembling it.
NOTE: Make sure to put the flow cell in a paper or plastic
container when cleaning it.
The use of a glass container may scratch the cell
or preclude obtaining the desired performance
from the instrument.
