Instrument Overview

The water quality microbial detector is an upgraded product developed and launched by our company in Shandong. It has a large touch screen instead of traditional buttons. The operation uses a biochemical reaction method to detect the ATP content. The ATP fluorescence detector is based on the principle of firefly luminescence. The ATP rapid bactericidal effect detection method is based on the ATP (adenosinetriphosphate) triphosphonic acid acyl glycoside detection principle, and uses the "luciferase-luciferin system" to quickly detect adenosine triphosphate (ATP). The ATP swab contains a reagent that can lyse the cell membrane, which can release ATP in the cell, react with the specific enzyme contained in the reagent, generate light, and then use a fluorescent illuminometer to detect the luminescence value. The number of microorganisms is proportional to the luminescence value. Since all living cells contain a constant amount of ATP, the ATP content can clearly indicate the amount of microorganisms and other biological residues in the sample, which is used to judge the sanitary conditions.

Functional features

Practicality - upper and lower limits can be set according to environmental testing needs to achieve rapid data evaluation and early warning;

By recording the relative light unit value (RLU) of the monitoring surface, the quality of environmental surface cleaning work can be assessed;

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

Fast speed - conventional culture method takes more than 18-24 hours, while ATP only takes more than ten seconds;

Feasibility - There is a clear correlation between the number of microorganisms and the ATP contained in the microorganisms. By detecting the ATP content, the number of microorganisms in the reaction can be indirectly obtained;

Operability - traditional culture methods need to be operated by trained technicians in the laboratory; and ATP rapid cleanliness detection is very simple and can be operated on-site by general staff with simple training;

Better experience - the test tube adopts a plug-in flexible design, which can be cleaned regularly for long-term use to extend the life of the instrument;

Data export - the instrument is equipped with a host computer software, which is connected to the computer through a data cable to output the stored data in the form of Excel tables.
