The patented technology Colifast AS ™ offers is comprised of unique media formulations and instrument detection systems, which significantly reduce the time from sampling to result. 

Traditional microbial testing in the laboratory is time-consuming, whereas Colifast AS™ offers rapid and simple test procedures that present results within only 2 to 12 hours. 
 No laboratory facilities or minimal skills in microbiology are required to perform the tests from Colifast.

The Chemical Reaction

The Colifast technology is based on a chemical reaction between a substrate in the growth medium and enzymes produced by the coliform bacteria. 
The bacterial enzyme β-D-galactosidase hydrolyses the substrate 4-methylumbelliferyl-β-D-galactoside, which results in the release of the fluorescent product 4-methylumbelliferone (MU).
