Abstract
An assay device comprising a centrifugation tube and, as a sliding fit therein, a less deep inner tube whose base has one or more apertures sufficiently large to allow the passage of particles. This device can be used in an assay for microorganisms in a liquid sample containing fatty material, which comprises centrifuging the sample and a clearing agent in the device, removing the inner tube containing the fatty material, removing at least substantially all of the liquid supernatant in the centrifugation tube, and determining the presence of ATP in the sedimented pellet.
Claims6
A method of separating fatty material in a centrifuged sample, from sedimented pellet and supernatant liquid, by placing said sample in an assay device wherein said method comprises use of an assay device comprising a centrifugation tube and, as a sliding fit therein, a less deep inner tube whose base has one or more apertures sufficiently large to allow the passage of particles;
- and recovering said fatty material.
An assay for microorganisms in a liquid sample containing fatty material, which comprises centrifuging the sample in a device comprising a centrifugation tube and, as a sliding fit therein, a less deep inner tube whose base has one or more apertures sufficiently large to allow the passage of particles, removing the inner tube containing the fatty material, removing at least substantially all of the liquid supernatant in the centrifugation tube, and determining the presence of ATP in the sedimented pellet as indication of the presence of microorganisms.
