Colitag™16-48 hour
widest testing window

Colitag™ is a Presence/Absence and MPN enzyme substrate test that provides 16-48 hour total coliform & E.coli determinations and detects 1 MPN of total coliform or E. coli bacteria per 100mL water sample. Coitag™ is relied upon in a growing market of over 24 countries.

Run it when you’re ready,
read it when you’re ready

Colitag™ offers unrivaled flexibility, allowing you to use one test instead of three to read your samples at any time within 16-48 hours. Eliminate the need to buy three separate tests and get the job done on your own time.

Improve your laboratory

Colitag’s bright blue fluorescence indicating a positive E. coli sample eliminates the need for time-consuming confirmations created by media that emits a less-intense fluorescence. This teamed with the flexible reading window allows you to streamline your lab processes.
