1, atp fluorescence detector (water quality microorganism detector) instrument can quickly detect the contents of microorganisms and bacteria in various water quality. The device is a brand-new upgraded product, which replaces the traditional buttons with a large screen touch screen. The operation used biochemical reaction method to detect ATP content, and ATP fluorescence detector used "luciferase-fluorescein system" to quickly detect adenosine triphosphate (ATP) based on firefly luminescence principle. ATP cotton swabs contain a reagent that can crack the cell membrane. This reagent can release ATP in cells and react with specific enzymes contained in the reagent to produce light. Then, the luminous value was detected by fluorescence photometer. The number of microorganisms is directly proportional to the luminous value. Because all living cells contain constant ATP, the ATP content can clearly indicate the number of microorganisms and other biological residues in the sample, which can be used to judge the sanitary situation.

2, instrument features:

Practicality-the upper and lower limits can be set according to the requirements of environmental testing, so as to realize rapid data evaluation and early warning and rapid surface cleanliness screening.

High sensitivity-10-15 ~10-18 mol.

Fast speed-the conventional culture method is 18-24 hours or more, while ATP only takes more than ten seconds.

Feasibility-the number of microorganisms has obvious correlation with ATP contained in microorganisms. By detecting ATP content, the number of microorganisms in the reaction can be obtained indirectly.

Operability-traditional culture methods need to be operated by trained technicians in the laboratory; The operation of ATP rapid cleanliness detection is very simple, and ordinary staff can conduct it on the spot after simple training.

Better experience-the test tube adopts plug-in flexible design, which can be cleaned regularly and used for a long time to prolong the service life of the instrument.
