About the nitrite reducing bacteria (nrb) tests / dipslides (box of 10)

NRB Test Kit

NRB metabolises nitrate / nitrite thereby reducing nitrite levels and producing ammonia. Both of these outcomes can lead to corrosion. 

Systems are often treated with nitrite / nitrate as a corrosion inhibitor. Since NRB reduces nitrite, the corrosion inhibiting abilities of the nitrite are then diminished. A by product of this metabolisation is ammonia. Ammonia is a compound that has corrosive properties. This makes NRB a two fold problem when it comes to corrosion and potential degradation of systems / equipment.

Our NRB tests are plastic tubes containing culture gel. The gel will turn pink when ammonia is present, indicating the presence of nitrite reducing bacteria. 

These tests come in a pack size of 10 slides / tests per box. 

  • Add 2ml of the test sample to the tube. To aid the user, 2ml of test sample can be determined by adding the sample up to the moulded line in the tube.
  • Incubate the NRB test / dipslide at 30 degrees C for up to 5 days. Check the test daily for the first three days.
  • If there is no colour change or gas bubbles after 5 days, this indicates a negative result.
