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

Colitag™ offers unrivalled flexibility, allowing you to use one test instead of three to read your samples at any time within 16-48 hours. Increase lab efficiency and get the job done on your own time.


Improve your laboratory
efficiency

Colitag’s bright blue fluorescence indicating a positive E. coli sample eliminates the need for time-consuming confirmations sometimes required by other enzyme substrate media with lower intensity fluorescence. This teamed with the flexible reading window allows you to streamline your lab processes.
