Rapid E. coli/coliform Testing in Water with Readycult® Coliforms 100
The EPA approved Readycult® method allows you to use the indole test for immediate E. coli confirmation saving you days of lab time and the expense of traditional testing. You'll also be able to respond more quickly to potentially dangerous situations. And you'll never have to worry about product integrity as Readycult® Snap Packs don't need to be refrigerated and have the longest shelf life in the market! (3 years from day of production.)
Just add a Readycult® Snap Pack to your sample and mix. Incubate for 24 hours at 35-37°C. If there is no color change the test is negative. (Turbidity does not indicate a positive test). Any color change in the broth to blue-green, even if only at the upper section, confirms the presence of total coliforms. A light-blue fluorescence indicates the presence of E. coli. If confirmation of E. coli is desired, the indole test can be performed directly in the same broth by adding Kovac's reagent (or Bactident® Indole). If a red ring appears immediately you have positive confirmation.
