Description
Coliforms chromogenic Agar (ISO) is a dehydrated culture medium for microbiological detection and enumeration work aligned with ISO 9308-1 and ISO 11133. The 500 g unit is intended for laboratories performing microbiological analyses of water and related hygiene-monitoring tasks where chromogenic differentiation of coliform organisms supports clear colony reading. With a pack weight of about 0,604 kg, the medium suits routine media preparation in water-testing, environmental, and quality-control settings that follow standardized nutrient-media practice. Chromogenic agar formats help analysts distinguish target colonies under established ISO workflows while maintaining consistent medium performance across batches. Offered by manufacturer Carl ROTH, this product sits within nutrient media used for the examination of water and broader microbiological analysis programmes. It is suitable for institutions that need a defined ISO-referenced coliform medium in a practical laboratory pack size for ongoing surveillance, compliance testing, and method validation activities.
