Abstract
A sample preparation device for precisely measuring a sample volume, mixing the sample with a reagent and then separating out any resulting precipitant from the sample. In using the device, the sample is nonquantitatively dispensed by the user and is volumetrically delivered by the device using a positive displacement method. No vortexing or shaking is required and the sample and reagent are precisely and reproducibly mixed automatically.
