This kit has been designed to allow the analyst to perform a very simple colorimetric analysis to determine the ammonia nitrogen concentration of their freshwater sample. The analysis yields an easily identifiable color transition that can be compared with the included color key to determine the concentration in your sample. The kit contains everything an analyst would need to perform a water analysis either in the laboratory setting or out in the field. Kit contains enough materials to perform 40 tests. Concentration Reader Range: 0, 0.25, 0.5, 0.75, 1.0, 1.5 and 2.0 mg NH Higher concentrations can be tested using a dilution of the water sample with DI water (not supplied) Aligned to the Next Generation Science Standards (NGSS)* Disciplinary Core Ideas: PS1.A; PS1.B Performance Expectations: MS-PS1-2 Cross Cutting Concepts: Structure and Function Engineering Practices: Developing and Using Models Kit Contents: 12 Plastic Pipettes 3 Reaction Vessel 3 Collection Bottle 1 Measuring Tube 15mL Ammonia Test Solution #1 15mL Ammonia Test Solution #2 15mL Ammonia Test Solution #3 Color Code Indicator Chart DOT Info: Small quantity exemption 173.4 THIS PACKAGE CONFORMS TO 49 CFR 173.4 for domestic highway or rail transport only *”Next Generation Science Standards” is a registered trademark of Achieve.
