Disclosed is a method for centrifuging serum which comprises the steps of introducing a barrier having an elastic porous member at least as its principal part into a blood-collecting tube and centrifuging serum, the elastic porous member having a porosity of 40 % or more, a continuous-pore size of 50 to 400 mu , and a cross-section larger than that of the blood-collecting tube. Also disclosed is a barrier (3) to be introduced into a blood-collecting tube (1), comprising an elastic porous member having a porosity of 40 % or more, a continuous-pore size of 50 to 400 mu , and a cross-section larger than that of the blood-collecting tube (1), the bottom portion of the elastic porous member preferably being a relatively hard portion (100, 111) with smaller outside diameter. |
