ATP fluorescence rapid detector detection principle

The DP24859 ATP Fluorescence Rapid Tester is an affordable and highly adaptable fluorescence detection system. It utilizes a single instrument platform to collect, analyze, and report various types of test data, offering ease of use, flexibility, and high accuracy. This device is ideal for rapid surface cleanliness testing in medical environments, including the surfaces of equipment and the hands of personnel. It is also suitable for monitoring surface hygiene and controlling microbial growth. The tester works by detecting adenosine triphosphate (ATP), which is present in all living cells. Using a swab, it can quickly perform both qualitative and quantitative tests for coliforms, *E. coli*, and *Enterobacter*. The method 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 immediate results. Key features include: - **High sensitivity**: Detects as low as 5 × 10⁻¹⁵ mol of ATP. - **Fast results**: Completes tests in just 15 seconds, compared to traditional culture methods that take 18–24 hours. - **Strong correlation**: There is a clear relationship between microbial load and ATP levels, allowing indirect estimation of microorganisms. - **User-friendly**: Unlike conventional lab-based methods, this device can be operated on-site by trained staff with minimal instruction. - **Comprehensive display**: Features a large, clear LCD screen for easy reading. - **Wide detection range**: From 0 to 9999 RLUs or 0 to 99999 RLUs. - **Accurate readings**: ±5% or ±5 RLUs interference. - **Environmental tolerance**: Operates between 5°C and 40°C, with humidity ranging from 20% to 85%. - **High ATP recovery rate**: 90–110%. - **Multiple detection modes**: RLU and coliform screening. - **Customizable settings**: Supports up to 50 user IDs, 251 result limits, and 2000 memory entries. - **Automated functions**: Includes automatic pass/fail judgment and statistical pass rate tracking. - **Built-in self-calibration**: Ensures consistent performance over time. - **Quick startup**: Self-test upon boot takes only 30 seconds. - **Connectivity**: Equipped with RS232 interface for data transfer to a PC. - **Power options**: Uses two standard AA batteries or rechargeable lithium batteries. - **Long standby life**: Up to 6 months at 20°C. - **Multilingual support**: Comes with a Chinese operation manual. - **Stable reagents**: Includes stable liquid luciferase and wet swabs for sample collection. **Included in the package:** - Host unit - Leather case - RS232 data cable - USB communication cable - Warranty card - Chinese user manual - Installation CD - Random reagent system and consumables - 20 ATP sample collection devices - Detailed operation instructions document This device is perfect for healthcare professionals, food safety inspectors, and laboratory technicians who need fast, reliable, and accurate microbial testing on the go.
