An apparatus and kit 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 a sampling portion and a handling portion. The sampling portion is adapted to acquire and releasably retain a predetermined volume of a liquid sample in one or more cavity that is not substantially defined by space between a plurality of fibers. The sampling device 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.

Apparatus for detecting ATP in a liquid sample

Apparatuses and kits for the detection of ATP in a liquid sample are provided. The apparatuses and kits comprise a liquid reagent composition comprising luciferin and a sampling device having a sampling portion and a handling portion. The sampling portion comprises a fibrous or a foam material and is adapted to acquire and releasably retain a predetermined volume of a liquid sample or a sample of residue from a surface. The sampling device comprises a dry coating or a liquid coating, the coating including an effective amount of a pH-adjusting reagent that, when contacted with a liquid reagent composition having a pH 6.8 or lower, changes the pH of the liquid reagent composition to 6.9 or higher. Methods of use of the apparatus or kit are also provided.
