AquaSnap is an easy-to-use ATP liquid test compatible with Hygiena luminometers. The device is available in two formats: Free and Total. AquaSnap Free measures dissolved ATP that is free in solution (non-microbial ATP). AquaSnap Total measures both free ATP in solution and microbial ATP (non-microbial and microbial ATP). The difference between Total and Free provides an indication of microbial contamination in the sample. The devices are often used for monitoring CIP systems, and for industrial water treatment systems such as cooling towers and closed water systems. Easy-to-use. Results in 15 seconds. Patented Snap-Valve™ design enables accurate results with less variation. 100% recyclable plastic. Honey dipper collects consistent 100 µl samples. 15 month shelf life at refrigerated temperatures.
