Whenever the cuvette is placed into the measurement cell, it must be dry outside and completely free of ¡ngerprints, oil or dirt. Wipe it thoroughly with HI731318 or a lint-free cloth prior to insertion. Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette. Do not let the reacted sample stand for too long after reagent is added, or accuracy will be lost. After the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.
