Cleanliness Detector

Product Introduction

This device is a newly upgraded product. It uses a biochemical reaction method to detect the ATP content. Based on the firefly luminescence principle, the ATP fluorescence detector uses the "luciferase-luciferin system" to rapidly detect adenosine triphosphate (ATP). The ATP swab contains a reagent that can lyse cell membranes, releasing intracellular ATP, which reacts with the specific enzyme contained in the reagent to produce light. A fluorescence illuminometer is then used 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, and is used to judge the hygiene status.

Instrument Applications

The ATP fluorescence detector is widely used in bacterial and microbial detection, medicine and health, food safety, market law enforcement, surface cleanliness detection, medical epidemic prevention, water quality and water administration, production line hygiene, industrial water treatment, environmental protection testing, customs entry-exit quarantine and other law enforcement departments, and many other industries.

Instrument Characteristics

• Practicality — upper and lower limits can be set according to environmental detection requirements, enabling rapid data assessment and early warning, and rapid screening of surface cleanliness.
• High sensitivity — detection accuracy 1×10⁻¹⁵ to 1×10⁻¹⁸ mol ATP.
• Fast speed — conventional culture methods take more than 18-24 h, while ATP takes only a dozen seconds.
• Feasibility — there is a clear correlation between the number of microorganisms and the ATP contained in microorganisms. By detecting the ATP content, the number of microorganisms in the reaction can be indirectly derived.
• Operability — traditional culture methods need to be operated in a laboratory by trained technicians, whereas ATP rapid cleanliness detection is very simple to operate and can be performed on site by ordinary staff after simple training.
• Strong interactivity — Android high-sensitivity touch operation and a high-speed data processing chip provide faster running speed and stronger stability.
