The Enterolert-DW Test, coupled with the Quanti-Tray system, provides quantitative confirmed results in 24 hours. The newest IDEXX enterococci test was developed specifically for the detection of enterococci in drinking water

Enterolert-DW uses a Defined Substrate Technology (DST) nutrient indicator to detect enterococci. When coupled with the IDEXX Quanti-Tray System, Enterolert-DW provides quantitative confirmed results in 24 hours.

Enterolert-DW utilises ortho-nitrophenyl-D-glucoside as a nutrient indicator and incorporates a specifically designed blue background colour in its formulation. When the enzyme-substrate is metabolised by enterococci, the sample turns from blue to green to indicate detection. Any change from the original colour to green is considered a positive result. No ultraviolet light source is required.
