In preparing a karyotype, a blood sample is centrifuged to separate the blood cells from the plasma. The plasma is discarded and a hypotonic solution is added to make the cells swell. The solution is centrifuged again. A drop of this material is added to a slide, dried, and stained. The slide is viewed and photographed. Based on this procedure where is the best place to discard the plasma?
