RheoSense, Inc. Proudly Announces e-VROC™ Viscometer

RheoSense, Inc. (San Ramon, CA) – is proud to announce a new addition to the VROC™ family, e-VROC™ viscometer! Coupled with the same small sample requirements and a wide dynamic range, e-VROC™ maintains the precision and accuracy of the m-VROC™ viscometer with one slight twist: the capability of measuring apparent extensional viscosity.

Extensional or elongational viscosity is ideal for
studying the complex properties of many fluids usedin industrial applications. By monitoring the sample flow through a microfluidic contraction, the system measures the pressure upstream and downstream of a contraction using the MEMS pressure sensors and registers changes in the flow. The fluid experiences shear flow in the straight channel and then an almost constant extension in the contraction zones as depicted in figure 1.

Application Corner: Protein Stability

RheoSense, Inc. (San Ramon, CA) — is pleased to announce a publication of a detailed web page on protein stability . The following page contains application notes on various protein stability topics and the usage of RheoSense viscometers to measure drug stability.

Protein stability is an important factor in R&D. Researchers focus on stabilizing proteins so that there will be no serious side effects. Temperature is a critical aspect in protein formulation since an increase in temperature can cause protein to lose its tertiary and secondary structures. As it continues, proteins begin to aggregate and can cause small changes to viscosity.
