SRB Bacteria Test Bottle
SRB Bacteria Test Bottle
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.
The liquid in srb-hx-14 and srb-hx-7 sulfate reducing bacteria test bottles turns black, with black precipitate or iron nail turns black, indicating the growth of sulfate reducing bacteria.
