Product Number: C33911
Call to Order
Grades 6-8. Designed for an analyst to perform a simple colorimetric test to determine the nitrite and nitrate concentrations of fresh water samples. The reaction yields an easily identifiable color transition that can be compared with the colors on the color chart determining the concentrations. Identified nitrite and nitrate values are 0.0, 0.25, 0.5, 1.0, 2.0, 4.0, 6.0, 8.0, and 10.0 PPM. The kit contains everything an analyst would need to perform a water test either in the laboratory setting or out in the field. Contains enough materials to perform 40 tests. Contents: 60 ml Griess reagent, 0.5 g cadmium metal powder, six plastic pipettes, three reaction vessels, three collection bottles, one measuring tube, one package of wooden dowels, and one nitrite and nitrate color chart.
