Patent
CA 2009466
A composition is provided for use, particular- ly in evacuated blood collection tubes, as a blood partitioning composition. The composition is useful in providing cleaner serum or plasma samples for biochemical tests, including a wide range of drugs. The composition includes a balanced dual resin component which provides the desired hydro- phobic property while simultaneously controlling viscosity and the specific gravity, which component is comprised of poly-alpha-pinene resin which provides good drug recovery but low density with a chlorinated hydrocarbon resin which provides the proper density level while maintaining the desired hydrophobic property of the resin blend. Thixo- tropic property is achieved by adding silica and network stabilizer in the composition.
