Abstract
The invention relates to a method and a blood bag system for the separation of blood components from whole blood, the blood being tapped into a blood bag, which is then centrifugated to form an upper layer containing blood plasma, a lower layer containing red blood cells and an intermediate buffy coat layer, and it is characterized in that the blood is tapped into a first blood bag (1,28) having outlets both at the top (7,30) and at the bottom (1,33), and that after centrifugation the layer containing blood plasma is pressed out through the upper outlet (7,30) of the blood bag while the layer containing red blood cells is pressed out through the lower outlet port (10,33) of the blood bag, so that substantially only the intermediate layer remains in the bag (1,28).
