AquaVialTM EX is a rapid, highly sensitive water quality screening tool designed to identify E.coli at sampling point.
AquaVialTM EX is a field-portable screening test that detects E.coli bacteria concentrations above 1 CFU/10ml (one bacterium per 10 milliliters) within 7 hours of incubation and as low as 1CFU/100ml, when incubation is extended to 9 hours. The dual vial system allows for duplicate testing at each sampling point and ensures reliable results are obtained every time
AquaVial™ EX Solution
How Does AquaVial™ EX Work?
AquaVialTM EX uses a system of dyes designed to change color in the presence of Beta-Glucoronidaze, an enzyme produced by the large majority of E. coli strains. The sample is incubated in a selective nutrient media and for 5 to 9 hours (depending on the sensitivity level desired). After the incubation, a contrast agent is added that kills the live bacteria and reacts with metabolites produced during the incubation. This reaction results in a change of color of the solution from yellow to indigo. The intensity of the color produced is directly proportional to the number of bacteria found in the sample.
Detection Limit
Incubation Time / Sample volume | 1ml | 10ml | 100 ml |
---|---|---|---|
5 hours | 1000 CFU/ml | 1000 CFU/10 ml | 1000 CFU/100ml |
7 hours | 10 CFU/ml | 10 CFU/10 ml | 10 CFU/100ml |
9 hours | 1 CFU/ml | 1 CFU/10 ml | 1 CFU/100ml |
