Intended Use
Kits for real-time and continuous detection and quantification of Escherichia coli or intestinal Enterococci in bathing recreational waters, used with the XplOrer64 System. Requiring only few minutes to handle the filtration step and processing up to 64 samples simultaneously in random access, the CheckN’Safe E. coli/Enterococci test is simple to perform and provides a rapid real-time quantitative result. The test is based on a continuous real-time impedance technology. The higher the bacterial concentration, the sooner the time to result, giving the E. coli/Enterococci concentration in the water sample.
Principle
CheckN’Safe is a culture medium and analysis is based on a variation of impedance. Each vial contains a specific selective enriched broth culture medium that enables specifically the growth of the targeted environmental strains. It contains 2 electrodes to measure the variable signal of impedance during growth. The detection and data analysis processes are optimized for the use with the XplOrer64 System. This test allows the detection of 500 E.coli/100 ml within 6 hours and 370 Enterococci/100 ml of bathing water within 9 hours (warm-up time included), whatever the origin of the bathing water sample is (marine seawater or fresh surface water).
