How does it work?

The AccuPoint® Advanced ATP samplers utilizes ATP bioluminescence to determine the cleanliness of test samples. ATP is a chemical compound found in all living cells, including bacteria, food debris, yeast, and mould. Bioluminescence is a chemical reaction that produces light. ATP bioluminescence occurs when ATP from a sample comes into contact with luciferase, an enzyme found in fireflies, and luciferin, a substrate. The amount of light emitted in this reaction is proportional to the amount of ATP in a sample. After a sample is taken, the sampler is pressed into its cartridge, breaking its seal and initiating the mixing of reagents. The reaction takes place within the cartridge, and a detector in the instrument measures the amount of light produced. The reading is displayed on the screen in RLUs. According to pre-set limits, an icon is displayed indicating a pass, marginal, or fail result.
