Colitag Presence/Absence Test

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.

Colitag requires:

• Colitag 100ml Presence/Absence Test Pack 

• Sterile Graduated Containers  

• A small incubator at 35 degrees

• A UV lamp is required for testing for E coli
