Enterolert-DW
Detects enterococci in drinking water
The Enterolert-DW Test, coupled with the Quanti-Tray system, provides:
- More accurate and specific compared to ISO 7899-2 and MoDW 2006, part 5.
- Confirmed results in 24 hours.
- Same easy-to-use platform as the Colilert-18 Test.
The Science
How the Enterolert-DW Test works
The Enterolert-DW Test uses a Defined Substrate Technology (DST) nutrient indicator to detect enterococci. When coupled with the IDEXX Quanti-Tray System, the Enterolert-DW Test provides quantitative confirmed results in 24 hours. The Enterolert-DW Test utilizes ortho-nitrophenyl-β-D-glucoside as a nutrient indicator and incorporates a specifically designed blue background color in its formulation. When the enzyme substrate is metabolized by enterococci, the sample turns from blue to green to indicate detection. Any change from the original color to green is considered a positive result. No ultraviolet light source is required.
