Read afternoon samples the next morning—before the next day’s samples arrive. Lift boil water alerts in 18 hours. Provide results in record time for real estate, new well, and new construction samples. Read Friday samples early Saturday, leaving the rest of the weekend free. Overview Easy Ease of use simplifies training. Unit-dosed packaging eliminates media preparation. No repeat testing due to clogged filters or heterotrophic interference. Rapid Under 1 minute hands-on time. No confirmations needed. No glassware cleaning or colony counting. Accurate Identifies E. coli specifically, eliminating unnecessary public notification due to non-target organisms. Suppresses up to 2 million heterotrophs per 100 mL. Eliminates the subjective interpretation found in traditional methods. Detects a single viable coliform or E. coli per sample. Economical Minimizes evening and weekend work. Up to 15-month shelf life at room temperature. Flexible Can be used for presence/absence (P/A) or quantification testing with Quanti-Tray and Quanti-Tray/2000. Science How it works The Colilert-18 test uses a proprietary Defined Substrate Technology (DST) nutrient indicators ONPG and MUG to detect coliforms and E. coli. Coliforms use their β-galactosidase enzyme to metabolize ONPG and change it from colorless to yellow.
