APPARATUS FOR DETECTING ATP IN A LIQUID SAMPLE

摘要

An apparatus (1000) and kit (1000) for the detection of ATP in a liquid sample is provided. The apparatus and kit comprise a liquid reagent composition comprising luciferin and a sampling device having (100) a sampling portion (30) and a handling portion (20). The sampling portion (30) is adapted to acquire and releasably retain a predetermined volume of a liquid sample in one or more cavity (32) that is not substantially defined by space between a plurality of fibers. The sampling device (30) comprises a dry coating that includes an effective amount of a pH-adjusting reagent that, when contacted with a liquid reagent composition having a pH of about 6.8 or lower, changes the pH of the liquid reagent composition to 6.9 or higher. A method of use of the apparatus or kit is also provided.
