Coliforms and E.coli Tests (25 Tests)

Intended Use

Escherichia coli and Coliforms are traditionally used as indicator organisms for faecal contamination in water and other environmental samples. Detection of these organisms usually points to poor hygiene at some stage in the production process or pollution of water at source. 

Based on a traditional test for Coliforms and E.coli, the Coliform Isolation swab provides a simple method for detecting these organisms - showing a definite colour change from purple to yellow when the target organisms are present.

• Always try to sample the same surface are (100 cm² or 200 cm²), and be consistent in your sampling.
