July 22, 2013 -- RheoSense, Inc. announces another measurement capability to its unrivalled flagship viscometer, m-VROC.

The m-VROC is now equipped with the highest resolution to detect and measure Intrinsic Viscosity, a capability indispensable 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.

RheoSense m-VROC, the high-precision, industry-leading viscometer, excels at measuring intrinsic viscosity. RheoSense has been at the forefront of viscometry for smallest sample volume and measured in the shortest amount of time.

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 is easy and fast, requiring just 20 microliters and takes only a few minutes.

About RheoSense Inc.

RheoSense is a global high-tech company based in Silicon Valley. Our innovative m-VROC & microVISC instruments feature patented Viscometer/Rheometer-on-a-Chip (VROC) technology. Utilizing state-of-the-art MEMS and microfluidics breakthroughs that redefine the viscometry industry, our instruments offer the smallest sample volume per measurement coupled with exceptional ease-of-use and accuracy. We are the leader in biotechnology, pharmaceutical, and the emerging protein therapeutics industries. RheoSense instruments have been rigorously tested, approved, and adopted worldwide by Fortune Global 500 companies and leading research universities.
