11G-24 UltraScan VIS
To operate the flow-through cell assembly,
1. Standardize the instrument in a transmittance mode. The flow-through cell should be filled with
distilled water or another clear solvent to set the top of scale.
2. Inject the sample to be measured into the cell.
Note: The pressure used to inject the liquid into the cell should not exceed 1 atmosphere (14.7
lbs/in
2.
)
3. Proceed with sample measurement.
4. Drain the sample from the cell.
CAUTION
Do not standardize in RSEX mode with the flow-through cell assembly in place. This
may damage the cell and/or instrument.
The flow-through transmission cell may need to be cleaned periodically. Use a glass cleaner on the
exterior of the cell and distilled water pumped through the cell for the interior.
Holder for Small Volume Transmission Cells and 10-mm Small Volume
Transmission Cells
This option provides a holder for a cylindrical small volume transmission cell. Each cell is shipped with
two caps, one that is solid and screws on, and one that is threaded and covered with injectable Teflon

.
The cell has an outside diameter of 28 mm, an inside diameter of 25 mm, and a 10-mm path length. The
cell and holder together are used for total transmission measurements of small quantities of liquids.
