Testing with Hach's m-ColiBlue24 Broth requires no fluorescent lamps or color comparators—interpretation of the results is done by easy, visual identification. E. coli colonies are blue, other coliforms are red; total coliforms are the sum of the two. Results are enumerated directly, which is more accurate and precise than statistical-based tests, such as Multiple Tube Fermentation (MTF) and Most Probable Number (MPN).
This method has been approved by the EPA for monitoring drinking water and wastewater and can be used to detect coliforms in other types of waters—bottled, surface, ground, well and recreational (fresh or marine) as well as process water for ultrapure chemical processing.
Hach Company not only offers m-ColiBlue24, but also the total solution for your microbiology testing needs, including other media (m-Endo, m-FC), Petri dishes, membranes, filtration equipment and manifolds and field testing equipment.
