The Principles of the Colipate
The ColiPlate water testing kit is a rapid, convenient and accurate test for qualitative and quantitative measurement of Total Coliforms and E. coli bacteria. The test is based on an EPA approved methodology which is designed to meet regulatory guidelines for untreated water, surface water, recreational water, processing water and wastewater. The ColiPlate test quantifies the density of the target bacteria (Coliforms and E. Coli ) ranging from less than 3 to 5,000 colony forming units (cfu’s) per 100ml sample.

The ColiPlate utilizes proven nutrient indicators X-Gal and MUG to detect viable Coliforms and E. coli bacteria as well as selective media to stimulate the growth and indicators for chromgenic and fluorogenic enzymes. The substrates react with the enzymes produced by the Coliforms (Beta-D-galactosidase) and the E. coli (Beta-D-glucoronidase) resulting in a blue/green formation of colour, and a fluorescence emission by the Coliforms and E. coli respectively.
