A fluid separation device and in-line orifice mixer system is disclosed. The fluid separation device utilizes a syringe, which is used for obtaining a fluid sample such as blood, in a centrifugation device, and further utilizes the syringe as a source of a separated fluid portion for storage and transfer for subsequent applications. The syringe containing the separated portion source and a second syringe containing a second source are connected to the in-line orifice mixer device. The mixer device comprises a plurality of orifice walls each providing an orifice non-aligned with adjacent orifices to homogeneously mix the plurality of components. The mixer device may further comprise an exit orifice wall with one or more orifices for discharge of the homogeneous mixture.

Apparatus and method for measuring the shear viscosity of a fluid urges sample fluid through a gap between a sleeve having an axial passage and a pin extending axially into the passage in the sleeve to subject the sample fluid to shear while measuring the axial force tending to move the pin and the sleeve axially away from one another, the axial force being indicative of the shear viscosity of the sample fluid.
