ABSTRACT:
An apparatus for separating blood is provided with a closed end and a thixotropic gel-like sealant with a specific gravity intermediate between the gravities of serum and clot phases. A cavity is formed on the upper surface of said sealant. The sealant consists essentially of an .alpha.-olefin-dimaleate copolymer having a viscosity from 10,000 to 120,000 c.p. (25.degree. C.), to which a viscosity-specific gravity adjusting agent is added to adjust the specific gravity to 1.035-1.055. The cavity is formed in such a size that diameter of the upper surface is from 0.15 to 0.7 times the inner diameter of the apparatus and its depth is from 0.13 to 0.65 times the thickness of said sealant.
