It can be used for rapid measurement of surface cleanliness of medical system objects and operators’ hands. It can also be used for Surface Cleanliness Measurement and microbial growth control. The equipment uses chemical reaction to detect ATP and ATP swab to collect samples. ATP swabs are soaked in buffer solution, which helps to extract biological material (ATP) from dry or wet surfaces. The swab also contains a reagent that can break through the biofilm and expose the organisms that may exist under it. After specimen collection, the swab should be immersed in a volume agent that can release ATP from the cells. Then the ATP released from the cell and the ATP smeared from the surface of the device react with ultrasnap’s unique liquid reagent.
