The Ensure system with the Microsnap test devices can do ATP rapid hygiene monitoring as well as rapid Coliform and E.coli testing. It can detect one Coliform or E.coli organism in 8 hours. This system uses the inherent metabolic profile of groups of bacteria to evaluate their growth rate enzymologically leading to an enumeration of the starting innocula. The system uses a broth growth phase at a specified temperature (37C) to allow the bacteria to grow and develop to a sufficiently high number to allow the enumeration of the bacteria using specific enzymes. The enzymes are measured using a proprietary light generating substrate based upon traditional ATP bioluminescence. The system is robust and does not require the absence of ATP to allow the enzymes to be measured; hence exceptionally foul samples will not inhibit the reaction.
