Test® InstruSponge™ is an absorbent swab on a flexible wand that allows for easy maneuvering through complex internal channels of scopes and cannulated instruments to verify if there are any contaminants left after cleaning. Test® Instrusponge™ is used in conjunction with the ATP Complete Handheld Unit and Test® Swabs to give an accurate numerical measure of bioburden present.
The Ruhof ATP Complete® Contamination Monitoring System detects Adenosine Triphosphate (ATP), the universal energy molecule found in all animal, plant, bacterial, yeast, and mold cells. Product residues, particularly blood and bioburden, contain large amounts of ATP. Microbial contamination contains ATP, but in smaller amounts. After cleaning, all sources of ATP should be significantly reduced. When ATP is picked up by the tip of the Test® InstruSponge™ and brought into contact with the unique, liquid stable luciferase/luciferin reagent in the Test® Swab tube, light is emitted in direct proportion to the amount of ATP present. This is known as RLU or Relative Light Units.
The Ruhof ATP Complete® handheld unit measures the amount of light generated and provides information on the level of contamination in just 15 seconds. The higher the reading, the higher the level of contamination. Body fluids and tissue contain large amounts of ATP, and the high sensitivity of the ATP Complete enables very small residues of blood or tissue to be detected. The ATP Complete will detect 1/100,000th dilution of fresh blood, i.e. 0.2μg protein per swab.
