Maintenance
If the Turbimax CUE25 / CUE26 is not kept in the supplied case, when not in use, make sure that
the instrument has been turned off and that a clean sample cuvette fitted with a black light shield
cap has been placed in the optical well. This will ensure that a minimum amount of dust and debris
will be able to settle on the optics of the instrument.
Take all the necessary measures in time to ensure the operational safety and reliability of the entire
measuring system.
Maintenance work at the instrument comprises:
• Cleaning the cuvette
• Replacing the batteries
5.1
Cleaning the cuvette
Measurement cuvettes should be clean and free of marks or scratches. To clean a cuvette, proceed
as follows:
1.
Clean the interior and exterior with a detergent solution.
2.
Rinse the cuvette thoroughly 8 to 10 times with distilled or deionized water to eliminate the
possibility of detergent build-up and streaking.
3.
Store the cleaned and dried cuvette with the black light shield cap on the cuvette.
During normal operation you may use any typical glass cleaner along with a lint free cloth, or tissue,
to clean the outside of the cuvettes.
Condensation may appear on the cuvette when a sample is very cold and the relative humidity is
high. When this happens, the turbidity displayed may be higher than the actual turbidity due to light
scattered by the condensate on the cuvette. To alleviate the problem, either coat the cuvette with
an anti-fogging agent, or by running warm water over the cuvette for a short period of time to warm
the sample prior to measurement.
