How it works
ExactBlue Quick Check uses the same SPR (gold nanoparticle) chemistry as AquaVial Quick Check, optimized for the 1-hour dental-waterline workflow. Standalone visual readout — no reader needed. Calibrated to the CDC 500 CFU/mL dental unit waterline action threshold.
Collect 20-50 ml sample in a clean cup and concentrate it using the sample concentration kit provided
add concentrated sample to the test vial
Incubate 1 hour at 35-40°C
Read visible color change; pass/fail at 500 CFU/mL action threshold

Comparison
vs. traditional lab testing
Membrane filtration lab culture (ISO 9215 R2A media (7 day incubation))
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
Result in 1 hr vs the 24 hr Safe Check workflow or days-long lab send-out. Standalone (no reader required).
Detection chemistry
How it detects
SPR nanoparticle (gold colloid aggregation)
Uses surface plasmon resonance nanoparticles that change color when binding to bacterial cell-wall surface markers. Direct visual readout in 15-60 minutes.
