Abstract: After disposable pipette tips are used by an automated pipettor, they are released by the pipettor and fall into a waste container. When the waste container is removed to be emptied, the pipette tips are temporarily sequestered in a pipette tip holding station so that the automated pipettor may operate uninterrupted. After the waste container is replaced, the sequestered pipette tips are released by the holding station into the waste container.

Abstract: A computer-implemented method for determining the amount of an analyte in a sample comprises associating a nucleic acid amplification assay defined at least partly by user-defined assay parameters to the sample. The assay is performed by dissolving a unit-dose reagent with a solvent, wherein the solvent includes one or more amplification oligomers adapted to amplify a region of the analyte and the reagent does not include an amplification oligomer for performing the assay.
