If water samples are being tested with color-changing reagents, this bag can be used in place of an expensive bottle. The bag is made of a special barrier film suitable for use with enzyme-based methods that result in a chromogen and/or a fluorogen release when total coliform and E. coli are present. The special film prevents color change from permeating through the bag, contaminating another sample and creating a false positive, and making contact with a person’s skin if they are not wearing gloves. It is sterile, contains 10 mg of active sodium thiosulfate to neutralize chlorine, has 4 oz. and 100 ml fill lines, and is completely self-standing - no rack or holder is needed to keep the bag upright. If the sample is not chlorinated, this bag can still be used, the sodium thiosulfate will not affect the sample, it is nontoxic and nonnutritive, and only neutralizes chlorine if present. A free color comparator is included in every box.

The Coli-Test bag has been accepted by the EPA and is listed in the EPA Manual for the Certification of Laboratories Analyzing Drinking Water Section, 5th edition, January 2005.

The Coli-Test bag will save money three ways: less expensive than the bottle, lower freight charges, and reduced disposal costs. A box containing 100 bags measures 9 in. x 7 in. x 2 in. (23 x 18 x 5 cm), weighs 1 lb. (0.40 kg), compared to a box of bottles which has considerable more volume and weight.
