    Determination of bacteria in water

    Testing principle

    The principle of extinction dilution method was used in the determination of bacteria in water by test bottle method. The water sample to be determined will be injected into the test bottle step by step with sterile syringe for dilution, and each test bottle will dilute the number of bacteria in the water sample by 10 times. Until there is no bacterial growth in the last test bottle, then calculate the bacterial content in the water sample according to the dilution multiple.

    If the liquid in fb-hx iron bacteria test bottle shows black or brown colloid precipitation, or the red brown of the original liquid disappears into transparent clear liquid, it indicates the growth of iron bacteria.
