How it works
EZ E coli is a single-test pouch version of the AquaVial EX E. coli β-glucuronidase chemistry. Pre-loaded reagent in a 10 mL sample volume gives a 1 CFU/10 mL (≈0.1 CFU/mL) sensitivity. Read by visible color change — no lab.
Collect 10 mL water sample for testing and add it to test vial
Incubate
add the cartridge and release the liquid into the test
Read by visible color change; positive triggers retest/action

Comparison
vs. traditional lab testing
Membrane filtration lab culture (ISO 9308-1 / Standard Methods 9221)
Off-site, multi-day turnaround. Requires lab account, membrane filtration manifold, and qualified microbiology technician. Per-test cost from $40–$120 plus shipping.
On-site, same-day result
Easy single-use format — ideal for retail, vet, agriculture and food-processing surfaces where a 25-test kit is overkill.
Detection chemistry
How it detects
β-glucuronidase (10 mL sample volume)
Selective for E. coli via β-glucuronidase activity. The enzyme cleaves a fluorogenic/chromogenic substrate to produce a distinctive color change.
