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
47 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 Clean the sample cell
on page 18.
Note: Performance specifications may be different than shown in Specifications
on page 5 when test tubes, sample cells or ampules less than 25 mm are used.
Use a cell adapter when:
• Only a small quantity of sample is available.
• The sample to be measured is in an ampule that cannot be opened.
Refer to Table 4 for minimum sample sizes.
