3M™ Clean-Trace™ Water-Free ATP test is a single-use test device that contains sample collection rings for the collection of an aqueous sample (figure 1). The sample collection rings are coated with a wetting agent to aid in the collection of a liquid sample without the release of Adenosine Tri-Phosphate (ATP) from intact microbial cells. Upon activation of the test device, reagent in the cuvette of the test device reacts with ATP collected on the sample collection rings to produce light. The intensity of the light is proportional to the amount of non-microbial ATP. Measurement of the light requires the use of a 3M™ Clean-Trace™ NG Luminometer and the results are displayed in Relative Light Units (RLU). The test kit contains 100 ready to use test devices packaged as units of 10 per individual foil pouch.
Real-time Free ATP water hygiene test gives an objective indication of cleanliness in seconds.
Results measured using the 3M Clean-Trace NG or LM1 Luminometer and provided in Relative Light Units (RLU).
