When waiting 24–48 hours for a water test result isn't an option, AquaVial EX is the answer. Water treatment professionals, facility managers, and environmental operators face a critical gap: contamination decisions need to be made fast, but standard E. coli test kits take a full day or more. AquaVial EX closes that gap entirely — delivering confirmed E. coli results in just 5–9 hours, the fastest result time of any professional E. coli water test kit available. THE SCIENCE BEHIND THE SPEED AquaVial EX uses patented β-D-Glucuronidase enzyme-based technology — the same biological marker that ISO laboratory protocols rely on — to detect E. coli-specific bacterial enzymes directly in your water sample. This isn't a broad-spectrum test that flags harmless coliforms. It identifies the specific pathogen that regulators, health authorities, and ISO 9308-1:2014 use as the definitive indicator of fecal contamination. LABORATORY ACCURACY WITHOUT THE LAB When used in combination with AquaVial EX Total Coliform kit, results are equivalent to the ISO 9308-1:2014 international standard — the gold standard for E. coli and coliform detection. You get certified-equivalent accuracy delivered at field speed.
