RheoSense, announces another measurement capability to its flagship viscometer, m-VROC. The m-VROC is now equipped with high resolution to detect and measure Intrinsic Viscosity, a capability for all bio/pharma and polymer applications. Intrinsic Viscosity is a parameter used to determine the molecular size, weight, structure, and interactions among proteins, polymers, or macromolecules. Applications related to polymerization, degradation, interaction, and the stability of molecules all benefit by utilizing Intrinsic Viscosity. Measuring intrinsic viscosity is considered to be a more reliable method than light scattering to study and understand these phenomena. Until now, Ubbelohde or Cannon-Fenske glass capillary viscometer is one of the few viscometers that can measure intrinsic viscosity, with high repeatability. However, this method requires large amount of sample volume, usually more than 20 ml, and requires a long time for thermal equilibrium. All these issues are now eliminated with m-VROC. With RheoSense m-VROC, intrinsic viscosity measurement requires 20 microliters and takes a few minutes.
