Sterile 120mL Corning® coliform water test sample container with sodium thiosulfate tablet is used to test for the presence of coliform bacteria, microbiological contaminants in drinking water. Manufactured from pure polypropylene in a sterile environment and sterile-by-process. The one-piece container has an attached lid to reduce chance of contamination. Locking arrow assures sterility has not been compromised. The EPA fill line of 100mL +/- 2.5% makes it easy to use. A sodium thiosulfate tablet has been added to each container thus saving lab prep time and expense. Leak tight when sealed properly. An added benefit is the tie-down to protect from accidental opening that also serves as a custody seal. Sample label and instructions for use are supplied with each. A low cost, convenient product which meets EPA requirements. Coliform water test sample containers are also available without the sodium thiosulfate tablet. Corning 1700-100 & 1705-100.
The EPA approved Readycult® method for drinking water, 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). Vivid color change from yellow to blue-green takes the guesswork out of what constitutes a positive reaction. No need to gauge color intensity levels.
Just add a Readycult® Coliform 100 Snap Pack to your sample and mix. Incubate up to 24 hours at 34.5° to 37°C. If there is no color change, then 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 Reagent. If a red ring appears immediately you have positive confirmation of E. coli.
