Neogen’s AccuPoint 2 ATP Sanitation Monitoring System is a lightweight, handheld system that validates the effectiveness of a sanitation program by detecting food residues and microorganisms present on surfaces and in liquids. The system utilizes easy-to-use AccuPoint samplers, which automatically mix prepared reagents to quickly generate results.
The Test The AccuPoint system utilizes adenosine triphosphate (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 mold. 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 detected 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 cartridge contains a buffering solution, which flushes the ATP onto a pad containing the reagents. The reac¬tion takes place within the cartridge and a detector measures the amount of light produced. The reading is displayed on the LCD display in relative light units (RLU). According to preset limits, an icon is displayed indicating a pass, marginal or fail result. These limits are defined by the operator or by using the system presets.
AccuPoint ATP Surface Samplers
For use when sampling standard surface areas for the relative presence of ATP. Contains four foil packets of 25 samplers each for a total of 100 Samplers.
AccuPoint ATP Water Samplers
For use when sampling liquid for the relative presence of ATP. Contains four foil packets of 25 samplers each for a total of 100 Samplers.
AccuPoint ATP Access Samplers
For use when sampling ATP from narrow orifice surfaces such as the inside of filler heads or narrow tubes. Contains four foil packets of 25 samplers each for a total of 100 Samplers.
b) Accu Clean Protein Detection Surface Samplers
AccuClean is intended to be used as a simple method to determine the cleanli¬ness of food contact surfaces and equipment. The user simply rubs the sampler’s tip across a surface, places the sampler back in its cartridge and activates the test by depressing the plunger through the cartridge. After 10 minutes, the sampling tip is compared to a color chart to gauge the level of protein detected.
