| The donor bag was then centrifuged and the platelet-rich plasma transferred to a sterile plastic centrifuge bottle. |
| The tubes were centrifuged at 5000 rpm for 2 min, and the supernatant discarded. |
| These were shaken for 1 hour, then the solutions were centrifuged and the clear supernatant was pipetted into vials. |
| At steady state, cells were centrifuged and the fluorescence of the supernatant measured. |
| Bile must be centrifuged and examined under polarizing or light microscopy for detection of precipitates. |
| The mixture was gently pipetted and then centrifuged at 1000 rpm for 10 minutes. |
