Abstract: 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.

Abstract: An optical stack for sensing a presence of an analyte is provided. The optical stack includes a sensor material. The sensor material includes a first optical response including a first optical property having a second value in response to an excitation signal including the first optical property having a first value different from the second value. The first optical response includes a second optical property sensitive to the presence of the analyte. The optical stack includes a first optical film disposed proximate the sensor material and includes a third optical property having respective third and fourth values in response to the respective first and second values of the first optical property. The third value is different from the fourth value by at least a factor of 2.

Abstract: An aqueous composition, for example a composition for use as a lysis buffer, comprising zirconium oxide particles, a surfactant at a concentration greater than or equal to 0.005% (mass/volume), an organic, iron-chelating reagent having a first affinity constant greater than or equal to 104.2 with respect to ferric iron and a second affinity constant less than 103.8 with respect to magnesium (as determined in 20° C. deionized water at pH 8.45), and a buffer. The aqueous composition has a pH no less than 7.7 and less than 8.45, more particularly 7.8-8.3, in all cases when measured at 20° C. Methods of using the composition and kits comprising components of the aqueous compositions.
