ATP fluorescence rapid detector detection principle

The DP24859 ATP Fluorescence Rapid Tester is an affordable and highly versatile system designed for fast, accurate detection of ATP (adenosine triphosphate) in various environments. This instrument uses a single platform to collect, analyze, and report different types of test data, making it user-friendly, adaptable, and precise. It is ideal for monitoring surface cleanliness in medical systems, operator hands, and other critical areas where hygiene is essential. Additionally, it supports microbial growth control by detecting the presence of coliforms, *E. coli*, and *Enterobacter*. The device works through a chemical reaction that detects ATP, allowing for both qualitative and quantitative analysis of bacterial contamination. The process involves a bioluminescent reaction where specific enzymes in target bacteria react with a substrate to produce light. This light is then measured by the ATP fluorescence detector within 15 seconds, providing rapid and reliable results. Compared to traditional culture methods, which can take 18–24 hours or more, the ATP fluorescence system delivers results in just a few seconds. It offers high sensitivity (down to 5 × 10⁻¹⁵ mol), accuracy, and a clear correlation between microbial load and ATP content. Unlike conventional methods that require trained technicians in a lab setting, this device is easy to use and can be operated on-site by staff with minimal training. Key features include a large, clear LCD display, a detection range from 0 to 9999 RLUs, and a detection time of only 15 seconds. It also has a ±5% or ±5 RLUs interference margin, operates within a temperature range of 5°C to 40°C, and functions at humidity levels between 20% and 85%. The ATP recovery rate is between 90% and 110%, ensuring consistent and reliable performance. The device supports multiple detection modes, including RLU and coliform screening, and allows for up to 50 user IDs, 251 result limit settings, and 2000 data storage entries. It includes automatic pass/fail judgment, statistical pass rate calculation, and a built-in self-calibration light source. A 30-second self-test upon startup ensures the device is always ready for use. It comes equipped with an RS232 interface for data transfer to a PC, and it can run on two standard AA batteries or rechargeable lithium batteries. The device has a 6-month standby life at 20°C and includes a Chinese operation manual, installation CD, and a set of reagents and consumables. It also comes with a wet-integrated swab, an ATP sample collection device (20 units), and detailed operation instructions in a .doc file. The package includes the main unit, a leather case, an RS232 data cable, a USB communication cable, a warranty card, and all necessary accessories for immediate use. This makes the DP24859 an efficient and practical tool for maintaining hygiene standards in healthcare, food processing, and other sensitive environments.
