Colitag™ is a selective and differential ready-to-use, dehydrated medium for the simultaneous detection of total coliform bacteria and Escherichia coli in water.

Colitag is approved by the U.S. Environmental Protection Agency for compliance sample analyses as required by the Revised Total Coliform Rule. This method can be used as a presence/absence (P/A) test or for quantification of bacteria.

Colitag is capable of detecting 1 CFU of total coliforms or E. coli in a 100 mL water sample in 16–48 hours and does not require further confirmation or verification steps.

Colitag is intended to be used only for water quality research and analysis, by technically qualified individuals familiar with appropriate aseptic techniques for the identification of total coliforms and E. coli or under their supervision.
