Microbial detection instrument in water

Product introduction:

The microbial detection instrument in water can quickly detect the content of microorganisms and bacteria in various water qualities. The equipment is a newly upgraded product with a large touch screen instead of traditional buttons. The operation uses a biochemical reaction method to detect the ATP content. The microbial detection instrument in water is based on the principle of firefly luminescence and uses the "luciferase-luciferin system" to quickly detect adenosine triphosphate (ATP). The ATP swab contains a reagent that can lyse the cell membrane, release the 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.

Instrument characteristics:

Practicality - The upper and lower limits can be set according to the environmental detection needs, so that data can be quickly evaluated and warned, and surface cleanliness can be quickly screened.

High sensitivity - 10-15～10-18 mol

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; while 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.
