Why does CPI International CEO David Hejl call his Colitag water testing solution for coliforms and E. coli “Next generation technology?”

Well, because it is.

One of the leading drinking water testing media’s on the market, Colitag’s testing window of 16-48 hours is the industry’s widest. Coltiag is also the only one of its kind that can identify both MUG-positive and MUG-negative forms of E. coli.

Colitag also features our “Acid Resuscitation” patent, which identifies E. coli and coliforms that have been injured by chlorine but whose presence is still a threat.

Injured E. coli can be missed by other tests, but not with Colitag. Plus, Colitag also gives off a brighter fluorescence for water samples that contain E. coli so as to reduce the number of false positive tests that often result from other MUG-based methods of testing.  

Conducting a test with Colitag is extremely easy; it basically just requires a “snap and a pour” application. You simply snap open the blister and pour it into a 100 mL sample of water before incubation for 16-48 hours (Visit http://www.colitag.com/products/what_are.asp for our official instructions).

After the desired incubation period has passed, you simply take the sample and check to see if the sample’s color has changed from the normal colorlessness of water to yellow (it contains coliforms and possibly E. coli if it has). If the color of the sample is not yellow, then the water has tested negative for coliforms and E. coli. However, if the sample is yellow, then you next use a long wavelength (365 nanometer) UV Lamp to see if the sample becomes fluorescent blue. If, under the UV Lamp, the sample fluoresces blue, then it is positive for E.coli. 

In addition to being the premier testing method for coliforms and E. coli, Colitag is also economical and convenient, as it is the most affordable water testing solution on the market from a cost-per-test standpoint, has a 22-month shelf life, is used with disposable sample vessels (no glassware is required for Colitag’s procedure) and is compatible with other testing methods.

Colitag was EPA approved for use in an MPN format (assuming that a 100 mL sample of water is used for the test), and can also be used to test food and non-water beverage products for coliforms and E. coli.
