PURPOSE:To separate a blood serum with high yield and high purity, by taking in a high viscous sealant for blood separation within the range of a specified specific gravity in a vessel for the blood separation and arranging balls or granular bodies having the specific gravity higher than said sealant on the sealant and centrifuging it. CONSTITUTION:A sealant 7 mixed a polymer of high viscous (about 200- 10,000ps/sec. at 25 deg.C) liquid having about 1.03-1.08 specific gravity at 25 deg.C, produced by a monomer e.g. shown by the formula (R1 is H, CH3, R2 is C1-18 alkyl) with fine particles of silica, etc., is taken in a test tube for blood separation. One or more of balls or granular bodies of 0.01-5mm. grain diameter glass, zirconia, high specific gravity plastics, silica sand, etc., having higher specific gravity than the sealant, is placed on the sealant 7 and a blood 9 is put on it and centrifugation is carried out at 2,500-3,000rpm for about ten minutes. Hereby, a separating property of blood corpuscle 11 is good and a blood serum 10 without mixed blood corpuscle, is sampled with good yield at the time of taking out the blood serum 10 by decantation. |
