Adenosine Triphosphate, or ATP, is the energy molecule found in all living things, making it a perfect indicator when trying to determine if a surface or water is clean or not. Companies use ATP systems to rapidly verify surfaces cleaned thoroughly in food manufacturing and healthcare applications, and to ensure that biofilms are not developing on the surface that could affect quality. All-in-one ATP test kit is fitted with proprietary water collection device or swab, proprietary luciferase and liquid-stable reagent. Using with a commercial hand-held luminometer (such as portable ATP luminometer), the amount of ATP present in sample could be measured, providing information on the level of contamination in seconds.
