Abstract
Gel-like compositions useful for separating and partitioning whole blood into serum and clot portions. The composition comprises a polybutene liquid polymer having an inert high surface area inorganic filler dispersed therein, the filler being present in an amount sufficient to impart to the composition a specific gravity ranging from about 1.030 to about 1.090 and a viscosity ranging from about 200,000 to about 850,000 centistokes. When centrifuged in the presence of whole blood, the composition forms a chemical and physical barrier between the serum and clot portions.
