Water Microbiology
Colialert
IDEXX Colilert reagent is used around the world for the detection of coliforms and E.coli in water. Colilert, with its patented Defined Substrate technology® (DST®), is used in over 90% of all US State labs.
Colilert is, in fact, used more than all other methods combined (US, Canada and Japan drinking water markets).
Colilert is US EPA-approved and is included in Standard Methods for Examination of Water and Wastewater.
Colisure
Colisure coliform/E.coli results are definitive at 24 hours and can be read for up to 48 hours for convenience. This test's distinct magenta color means there's no mistaking a positive result. Colisure also suppresses high levels of non-coliforms including aeromonas.
