1. A system for collecting plasma from a donor comprising:
a) a venipuncture needle for withdrawing whole blood from the donor,
b) a blood separator for separating the whole blood into a plasma product and a second blood component comprising red blood cells;
c) a donor line coupled to the venipuncture needle for introducing whole blood from the donor to the blood separator;
d) a first pump for controlling flow through the donor line;
e) an anticoagulant line coupled to an anticoagulant source for combining anticoagulant with the whole blood;
f) a second pump for controlling flow through the anticoagulant line;
g) a touchscreen is provided for receiving input from an operator; and
h) a programmable controller configured to: determine a target volume of plasma product to be collected (TVPP) based on a weight of the donor, or based on a weight and height of the donor, and a percentage of anticoagulant in the target volume of plasma product to be collected (% ACTVPP) based on a pre-determined anticoagulant ratio (ACR) and a hematocrit (Hct) of the donor, control the system to operate a draw and return cycle to withdraw whole blood from the donor, add anticoagulant to the whole blood at a pre-determined ratio (ACR), separate the anticoagulated whole blood into the plasma product and the second component and to return the second component to the donor, and stop withdrawing whole blood from the donor and initiate a final return of the second blood component when a measured volume of plasma product in a plasma collection container reaches the target volume for plasma product, TVPP.
