A simple, reliable technique is required which enables the rapid, confirmed enumeration of both total coliforms and more importantly, E. coli.
Colitag is a pre-dispensed dry blended reagent formulation containing salts, nitrogen and carbon sources and specific indicator/nutrients for total coliform and E. coli. Positive samples are detected by a visible colour change. Performing the Coliform test is simple. The reagent is supplied in pre-measured dosage tubes for dispensing into sterile containers. Simply fill a sterile tube to the level, mix and then incubate at 35 ° C. The formation of a yellow colour in 24 hours or less indicates the presence of total coliforms. Positive tubes are then checked for the presence of E.Coli by looking for fluorescence under UV light.
