摘要： A syringe includes an outer cylinder, a gasket having at least one part which slidably contacts the inner wall of the cylinder and being made of an elastomer material including a block copolymer having styrene units at both terminal ends, and means for sliding the gasket inside the cylinder. The slidably contacting part is compressed inside the cylinder at a compressiblity C (%) of a predetermined range selected according to a particular inner diameter of the cylinder. The product of the total contact area S (mm.sup.2) at the compressibility C (%) of the contacting part with the inner wall of the cylinder with the compressibility C (%) is about 350 to about 900.

摘要： 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.
