Viscosity of Blood Plasma and Blood Serum

This application note demonstrates m-VROC^® capabilities to accurately determine the viscosity of blood plasma and serum. The viscosity measurements of either of these two fluids can be used to diagnose conditions caused by imbalance and disorders in the different proteins present in blood.

VROC^® technology allows for small sample measurements of viscosity over a wide rage of shear rates overcoming some of the major challenges posed by conventional methods:

• No evaporation, contamination, or protein aggregation at air-liquid interfaces.
• Highly accurate dynamic viscosity measurements with unsurpased repeatability.
• A viscosity measurement can be done with as little as 20 uL of sample
