ATP fluorescence detector based on the principle of firefly luminescence, the use of "luciferase - luciferin system" rapid detection of adenosine triphosphate (ATP). ATP swabs contain reagents that can cleave the cell membrane, the cell can be released from the ATP, and reagents containing specific enzyme reaction, resulting in the release of ATP. ATP swabs contain reagents that can cleave cell membranes, releasing ATP from the cells, reacting with specific enzymes contained in the reagents to produce light, and then detecting the luminescence value with a fluorescence illuminometer, the number of microorganisms is directly proportional to the luminescence value.
