A non-agar based medium designed to detect the presence of E. coli and other coliform in 100mL water samples. There is no need for an ultraviolet lamp to confirm the presence of E. coli. It can be used in 2 ways: 

1. Presence or absence determined by staining the culture medium 
2. MPN method, which measures the bacterial load 

Both ways have been validated by the AOAC RI

This chromogenic medium enables simultaneous detection and differentiation between E. coli and coliform in a single medium. 

Designed for use in broth form in the water filtration technique, for impregnating the pad. You can take an aliquot to prepare the exact quantity of broth you desire. It is also very economical, requiring only 2mL per test, as opposed to the 10-20mL needed for other culture media. 

With this chromogenic medium, colonies of E.coli develop an intense blue colour, simplifying the detection and enumeration of this important hygiene indicator.
