Factors that increased specimen throughput were (a) use of a gravimetrically calibrated manual pipette for the introduction of specimen into the ultracentrifuge tube; (b) use of open-top ultracentrifuge tubes that do not require sealing before ultracentrifugation; (c) use of a calibrated CentriTube Slicer; (d) use of a set of dedicated, preset, and gravimetrically calibrated manual pipettes for the reconstitution of the top and bottom fractions; and (e) placement of reconstituted fractions directly into analyzer-ready tubes or cups rather than volumetric flasks.
