Total Nickel Colorimetric Tubes, 0-0.5-1-2-5-10 mg/L (CAT#: STEM-AL-4036-ZJF)

Total Nickel Colorimetric Tubes is designed for rapid colorimetric screening of total nickel in water samples. The sealed tube contains the reagents required for the stated test procedure. Sample is drawn or added to the tube according to the supplied method. Color development is compared with a reference chart to obtain a concentration interval. The semi-quantitative format provides a rapid result without a separate analytical instrument. Individual tube construction supports transport and field operation. The documented reaction time and sample pH conditions should be observed. Sealed packaging helps preserve reagent integrity during storage. The product supports preliminary water-quality assessment across the stated range.
