Use a cell adapter

Many different test tubes, sample cells and ampules can be used to
measure samples when a cell adapter is used. Use a cell adapter when
the test tube, sample cell or ampule is less than 25 mm. Refer to
Accessories
on page 56 for the available cell adapters.
Use only test tubes and sample cells that are free of significant
scratches. Clean and apply silicone oil to all sample cells, test tubes and
ampules used with the cell adapters. Refer to
on page 19.
Note: Performance specifications may be different than shown in
on page 5 when test tubes, sample cells or ampules less than 25 mm are used.
