Note: The 2100AN reads slightly
different with cell adapters installed
because of the shorter path length
associated with the smaller
diameter sample cells. Refer to the
instruction sheet sent with the cell
adapters for additional information.
The adapters come with a tall light shield supplied for test tubes taller than the
standard cover.
Carefully select sample-cell glassware used with the adapters to be clean and free
of significant scratches. The same handling and cleaning care applied to the
standard 2100AN sample cells applies to the smaller cells (including the use of
silicone oil on the outside of the glass.
Use the Application Specific Calibration (ASC) ability of the instrument to
provide direct reading of results with cell adapters installed (instead of developing
a new calibration curve each time a cell adapter is used).
2.3.7.3 Installing and Removing Cell Adapters
Align the tab on the cell adapter toward the front of the instrument to install in the
instrument's sample compartment (see Figure 5).
Note: Do not force the adapter out
of the compartment; serious
instrument damage can occur.
Carefully pull the adapter straight up to remove. Slowly rotate the adapter
90-degrees counter-clockwise if the adapter catches.
