Cleaning of UV Flow Cell (A420, A421, A400, A401)
How to Replace UV Flow Cell (A420, A421, A400, A401)
To clean the clogged flow cell, flushing
in reverse works better. To start, prepare
a container for waste, then connect the
tubing from pump/column to the outlet
tubing of the UV detector, and let the
inlet tubing of the UV detector work as
the waste tubing.
Loosen the screw then pull the knob
to remove the flow cell.
