What is AquaVial™ PRO ?

main_picture2
AquaVialTM PRO is the ideal water quality screening tool for water treatment professionals.  Designed for monitoring microbial levels and biofilm formation for drinking water applications, AquaVialTM PRO is:

  • an economic and efficacious warning system for Legionella control
  • an efficacy confirmation of water disinfection systems and other high risk water sources (medical and dental)

AquaVialTM PRO detects total microbial (bacteria and fungi) and biofilm levels.  Detection limit can be adjusted from 100 CFU/ml to 500 CFU/ml or higher, depending on the application.

How Does AquaVial™ PRO Work ?

Aquavial PRO uses our proprietary surface cell wall recognition technology to detect and quantify microorganisms in water. The functionalized gold nanoparticles in our regent attach to specific areas of the cell surface, which results in a change in their Surface Plasmon Resonance (SPR) properties. This leads to a change in color from pink to purple at low cell concentration (500 to 2,000 CFU/ml), and from purple to clear at high cell concentration (over 2,000 CFU/ml).
how_clean_water3

Clean water

Pink: Only nanoparticles
present, no contamination.
how_contaminated_water3

Contaminated water

Purple: Aggregation of nanoparticles
with bacteria cells.
how_highcontaminated_water3

Highly contaminated water

Clear: The clearer the colour, the higher the microorganism count in the water, as all nanoparticles have been attached to bacteria cells.

Case Studies

Cooling tower

We conducted a study to confirm the ability of AquaVialTM PRO500 to produce results that meet the need for a fast, affordable, and accurate field test. This study investigated the changes of microorganisms in a cooling water tower over a five-week period.

Dental office

A study was performed in the dental clinic of a Canadian Dental College, to assess the bacteria levels in the dental chair water lines. Of the 24 chairs in the clinic, 12 were randomly selected for this test. The test was performed on three points for each chair.
