To perform a colorimetric test using the MACHEREY-NAGEL visocolor ECO Copper Test Tube, follow these steps:
1. Pour a 5 mL water sample into each of the measuring glasses using the provided plastic syringe. Place one measuring glass on position A in the comparator, and keep the other measuring glass empty for adding the reagents.
2. Add 5 drops of Cu-1 reagent to the empty measuring glass. Seal the glass and mix the contents.
3. Add 5 drops of Cu-2 reagent to the same measuring glass. Seal the glass and mix the contents again.
4. After 10 minutes, open the glass and place it on position B in the comparator.
5. Slide the comparator until the colors in the inspection hole on top match. Check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
6. After use, rinse out both measuring glasses thoroughly and seal them.
Please note that the measurement range of this test kit is 0.1–1.5 mg/L Cu2+. If your sample falls outside this range, you may need to adjust the sample or dilute it accordingly.
For further information and safety precautions, please refer to the instruction manual provided with the test kit.
