Merck Chromocult® Coliform Agar is a granulated chromogenic and differential culture medium for detecting and enumerating coliform bacteria and Escherichia coli in water and food samples. This 500 g pack produces a culture medium in which characteristic chromogenic reactions help distinguish target organisms after incubation. The listed preparation concentration is 26.5 g/L, and the specified pH is approximately 6.6–7.0 at 25 °C. Its applications include methods associated with ISO 9308, EPA procedures, and AOAC performance evaluations. The formulation supports simultaneous evaluation of total coliforms and E. coli in suitable matrices, reducing the need for separate preliminary differentiation steps. The material is supplied as dehydrated granules, not as ready-poured sterile plates. It is stored dry at 15–25 °C.
