„ TUBES AND CHAMBERS

The colorimeter uses one type of tube (Code 0290) for all test factors.
The handling of the tubes is of utmost importance. Tubes must be clean and free from lint,
fingerprints, dried spills and significant scratches, especially the central zone between the
bottom and the sample line.
Scratches, fingerprints and water droplets on the tube can cause stray light interference leading
to inaccurate results. Tubes that have been scratched in the light zone through excessive use
should be discarded and replaced with new ones.
Tubes should always be washed on the inside and outside with mild detergent prior to use to
remove dirt or fingerprints. The tubes should be allowed to air-dry in an inverted position to
prevent dust from entering the tubes. Dry tubes should be stored with the caps on to prevent
contamination.
After a tube has been filled and capped, it should be held by the cap and the outside surface
should be wiped with a clean, lint-free absorbent cloth until it is dry and smudge-free. Handling
the tube only by the cap will avoid problems from fingerprints. Always set the clean tube aside
on a clean surface that will not contaminate the tube. It is imperative that the tubes and light
chamber be clean and dry. The outside of the tubes should be dried with a clean, lint-free cloth or
disposable wipe before they are placed in the meter chamber.
Tubes should be emptied and cleaned as soon as possible after reading a sample to prevent
deposition of particulates on the inside of the tubes.
Variability in the geometry of the glassware and technique is the predominate cause of variability
in results. Slight variations in wall thickness and the diameter of the tubes may lead to slight
variations in the test results. To eliminate this error the tubes should be placed in the chamber
with the same orientation each time.
Chambers which have been scratched through excessive use should be discarded and replaced
with a new one.
