Rinse the cuvette by adding a small quantity of sample. Ensure that the plastic stopper is in place and shake the cuvette several times. Empty the cuvette.

Fill the cuvette with 10 mL of sample (up to the mark). Replace the plastic stopper and the cap.

Insert the cuvette into the holder and ensure that the notch on the cap is positioned securely in the groove.

Whenever the cuvette is placed into the measurement holder, it must be dry outside and free of fingerprints, oil or dirt. Wipe it thoroughly with HI731318 microfiber cleaning cloth or a lint-free wipe prior to insertion.

To avoid reagent leaking and to obtain more accurate measurements, close the cuvette first with the supplied HDPE plastic stopper and then the black cap.

1. Rinse the cuvette by adding a small quantity of sample. Ensure that the plastic stopper is in place and shake the cuvette several times. Empty the cuvette.

2. Fill the cuvette with 10 mL of sample (up to the mark). Replace the plastic stopper and the cap.
