This Biological Activity Reaction Test tests for Sulfate Reducing Bacteria. Kit includes nine tests. The change of black color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.

The test kit uses a color chart that measures Copper and Iron levels at 0.1, 0.3, 0.6 and 1.0 ppm. The test kit is simple to use with just adding 3 drops of Copper reagent to a 5 mL test tube of water then matching the color reaction to the color chart.

The Iron test is measured by adding 5 drops of Iron reagent along with an Iron TesTabs^® tablet to a 5 mL test tube of water then match the reacted sample water with the color chart. Included with the kit is an easy to read diagrammed instructions, test tubes, color chart and enough testing reagents to measure 50 tests.

This Chlorine test kit measures for Chlorine using the direct reading titrator method. Range/sensitivity is 0-10 ppm/0.2 ppm Cl.

This kit tests for Molybdate using Thioglycolate to form a yellowish color. Levels are measured using the Octa-Slide 2 viewer. Range/sensitivity is 30, 60, 90, 120, 150, 180, 240, 300 ppm Molybdate.

The pH value affects all mineral elements and the biological processes made available to plants from the soil. Accurate pH testing is essential to determine lime requirements and to insure that a mineral-rich soil is also a fertile one.

This soil test kit tests for pH levels using the Morgan method matching test results to color charts. Range and sensitivity is pH 3.8-8.4 in 0.2 increments (not for heavy clays).

This kit tests for Chloride in fresh water samples using the Direct Reading Titrator method.

This Potassium Test Kit tests for potassium using a turbidity reading tube. Range and sensitivity is 10, 20, 30, 40, 60 ppm K⁺.

Sodium tetraphenylboron reacts with potassium to form a white precipitate. The turbidity of the solution is proportional to potassium concentration which is measured in a calibrated tube.

A popular outfit for the testing and study of freshwater systems such as ponds, lakes, wetlands, rivers, streams, etc. This field-friendly outfit contains individual test modules for seven key freshwater test factors, water sampling bottles, three supplemental handbooks now available as a download, and data sheets. The handbooks include Limnology, A Study of Water Quality, and Investigating Water Problems.

Using the LaMotte Cyanide in Water Test Kit, the cyanide is first reacted with a chlorine donor to form cyanogen chloride, which then reacts with pyridine-barbituric acid to form a red-blue color. Levels are determined using the Octa-Slide 2 comparator.

This Biological Activity Reaction Test tests for Slime Forming Bacteria. Kit includes nine tests. The change of lime green color indicates a presence of bacteria within that sample. Interpretation is provided with the kit.
