Question: How is ATP detected by the SystemSURE II and Ultrasnap ATP device?
Answer:
Ultrasnap swabs are moistened with a buffer that aids in the removal of any biological material (ATP) on either a wet or dry surface, as well as to break through a biofilm and expose underlying cells. The ATP from microbiological cells in addition to free ATP from food residue is picked up from the equipment surface by Ultrasnap, and is then available to react with the unique liquid-stable reagent contained in the device. This reagent is derived from two naturally occurring firefly enzyme called luciferase. When this enzyme reacts with ATP, light is produced, detected and quantified by the SystemSURE II. The amount of light detected is directly proportional to the quantity of ATP, thus giving you a quantitative measure of surface cleanliness.
