COLIFAST TECHNOLOGY
Traditional microbial testing in the laboratory is time-consuming and require both laboratory equipment and knowledge - to work around this, Colifast AS has developed a technology to make water monitoring Automated, Remote and Rapid.
Colifast AS offers rapid and simple test procedures that is fully automated at site, with the same specificity as traditional microbial testing!
No laboratory facilities or skills in microbiology are required to use Colifast instruments!
The results will be presented within 2 to 15 hours, depending on the method and need of accuracy.
Enzyme
Reaction
1
Coliform bacteria produce specific enzymes (β-D-galactosidase or β-D-glucuronidase), which react with substrates in the Colifast growth medium.
2
Fluorescent Product Formation
The bacterial enzymes hydrolyze the substrate, releasing a fluorescent product called 4-methylumbelliferone (MU). The amount of MU increases as bacterial levels rise.
3
Fluorescence Measurement
The Colifast instruments measures the fluorescence signal, quantifying the number of bacteria based on MU concentration.
Selective
Bacterial Growth
4
Inhibitors in the growth medium prevent non-coliform bacteria from growing, ensuring accurate detection of target bacteria.
