The test consists of a screw-capped glass tube half filled with a selective microbiological culture gel that indicates the presence of nitrite-reducing bacteria in an aqueous sample by changing colour from Orange to Pink and also by producing gas bubbles. The sample is added to the test bottle which is kept warm (or incubated) usually at approximately 30 °C for up to seven days.
