The First Definitive Water Test System For Coliforms & E. coli

Colitag is the most versatile test ever! It has the widest approved testing window in the industry: 16 - 48 hours, greater selectivity for Total Coliforms and E. coli, a growth inhibitor for Aeromonas and Pseudomonas and is US EPA Approved for use in MPN format provided that the sum of all individual portions of the sample total 100mL.

Not only does Colitag^TM detect both total coliforms and E. coli bacteria in water samples - it's the only U.S. patented system that definitively tests for both MUG-positive and MUG-negative E. coli. That means accurate results you can be doubly sure of, without concern for false negative readings.

Colitag^TM also automatically resuscitates and then detects chlorine-injured bacteria, giving you a unique, highly sensitive tool for regulated site testing. And Colitag^TM does all this using a simple, ready-to-use medium that you combine with a water sample for results you can count on with complete certainty.
