Why won't my Nitrate Test kit work?

Why won't my Nitrate Test kit work?
When Nitrate #3 Reagent is exposed to heat, time and other environmental stresses it can become very hard to mix it properly. If the test kit has not been used for an extended period of time, or it has been stored at an elevated temperature for some time it may not mix easily.

If after the initial shaking some dust can still be seen through the bottle bottom or glass side wall. Be sure to check both areas for sedimentation. If there are particles or plating on the sides or bottom, you will need to perform a small operation.

Remove the dispensing top from the Reagent #3 bottle. Then take the pipette that comes with the test kit, and mix the contents manually. Ensure that all dust, particles and sediments are dissolved in the solution. Close the bottle. Clean the pipette thoroughly so there is no sediment or residue left.

After this manipulation, regular shaking should be enough to mix all the dust and any sedimentation back into the liquid.
