If there is gel separating the plasma from the red cells, it is not necessary to transfer the plasma to another tube. Follow directions in the centrifuge manual to set the centrifuge appropriately.If there is not gel separating the plasma from the red cells, transfer the plasma using a disposable pipette to another tube (pour off tube) being careful not to disturb the buffy coat.
