Paired Plateletpheresis with the CS 3000 Plus Blood Cell Separator Using the New 30 ml Low‐Volume Collection Chamber and the A‐35 Collection Chamber

Eight blood donors underwent paired plateletpheresis using the CS 3000 Plus blood cell separator. For each donor, two samples were run: one with the TNX-6 separation and the new 30-ml low-volume collection chamber (LVCC) and one with TNX-6 separation and the A-35 collection chamber. With the LVCC, 4.8 +/- 0.5 x 10(11) thrombocytes could be harvested, whereas 4.4 +/- 1.4 x 10(11) platelets (PLT) were collected with the A-35 chamber. The separation efficiencies were 51.7 +/- 6.6% for the LVCC and 43.8 +/- 10.7% for the A-35 chamber. The leukocyte contamination of the platelet concentrates was not statistically different.
