How it works
EZ Bacteria is the single-pouch version of AquaVial PRO500 — same SPR (gold nanoparticle) chemistry, packaged for single-use convenience. Result in 5 minutes at room temperature, pass/fail at the 500 CFU/mL action line.
Collect 10 mL water sample for testing and add it to test vial
wait for 5 minutes
add the cartridge and release the liquid into the test
Read color change; positive = ≥500 CFU/mL

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
Fastest standalone test in the line (5 min) — instant pass/fail without an incubator or reader.
Detection chemistry
How it detects
SPR nanoparticle
Uses surface plasmon resonance nanoparticles that change color when binding to bacterial cell-wall surface markers. Direct visual readout in 15-60 minutes.
