Repairing the Flow Cells
Cleaning the Flow Cell Parts
1 Pour isopropanol into the cell hole and wipe clean with a piece of
lint- free cloth.
2 Clean the windows with ethanol or methanol. Dry it with a piece of
lint- free cloth.
Reassembling the Flow Cell
1 Hold the flow cell cassette horizontally and place gasket in position.
Ensure both cell holes can be seen through the holes of gasket.
2 Place the window on gasket.
3 Place the peek ring on the window.
4 Insert the conical springs. Make sure the conical springs point towards
the window. Otherwise tightening the cell screw might break the
window.

5 Screw the cell screw into the flow cell and tighten the screw.
6 Repeat the procedure for the other cell side.
Next steps
1 Reconnect the capillaries.
2 Perform a leak test. If OK, insert the flow cell.
3 Perform “Wavelength Verification- Calibration” on page 108 to check the
correct positioning of the flow cell.
4 Replace the front cover.
Always use new gaskets.
The semi-micro #1 and #2 gaskets (items 6 and 7, “Semi-micro Flow Cell 6 mm / 5 µL” on
page 144) look very similar. Do not mix them up.
