Utilized as E.coli water test kits and coliform water test kits, the test system is designed for use by personnel familiar with appropriate aseptic techniques for the identification of total coliforms and E.coli. Training, which is available through Cell Biosciences, is recommended for those without a basic knowledge of microbiology.
