Recent papers confirm that the interface between air and protein solutions can lead to major errors in viscosity measurements of protein solutions and model synovial fluids!
RheoSense, Inc. (San Ramon, CA) — is proud to announce that VROC® technology, rectangular slit type viscometer, will officially be listed as a public standard under the US Pharmacopeia chapter <914> Viscosity — Pressure Driven Methods as Method I.
RheoSense, Inc. (San Ramon, CA) – The small sample viscometer, microVISC™, has been successfully validated for measuring serum viscosity in a clinical setting. It is essential to measure serum viscosity to analyze Hyperviscosity Syndrome (HVS).
Taking place from August 10th to the 14th in Durham, North Carolina, key industrial leaders and experts will convene to discuss the challenges and advancements in the field of biopharmaceutical and food industries.
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.
RheoSense, Inc. (San Ramon, CA) — has created an upscale web page on antibody therapeutics which includes newly enhanced application notes for RNA Therapeutics and Viscosity.
