"Which RheoSense Chip do I use for my Application?"

One of the common questions we get from our customers is, “Which chip do I use to test my fluid?” RheoSense has a variety of different chips and you may wonder which chip would be the best for your application. The m-VROC® has four different designations of chips: A, B, C, and E. These letter values reference the max pressure capability of the MEMS pressure sensors inside the microfluidic flow cell. With the A-series being able to measure the lowest pressures for low viscosity fluids, the E-series are able to measure the highest pressures for higher viscosities and higher shear rates.

VROC Initium Consumable Replacement Tips


My name is Ecko Chen, and I am the Mechanical Engineer here at RheoSense. My coworker Brandon has introduced a consumable list for the VROC® Initium maintenance in the previous post. I am going to expand a little on one of the most common consumable replacements --- The septa.

VROC Initium Tutorial Videos Coming Soon!

Hi there,

Starting this month, we're excited to announce the production of a new series of videos on our fully automatic, high throughput viscometer: VROC® Initium. In the first half of the series, our specialists and Initium production engineers explain step-by-step on how to correctly and safely set up and configure your instrument. Each instructional video will range anywhere from 3 minutes to 10 minutes. Each video includes tips or other helpful information to ensure optimal functionality and capabilities of your VROC® Initium. We are more than happy to answer any questions you may have, as well as creating additional media content topics suggested from you, our clients.

What Can System Suitability Do For You?

We frequently get the question, "how do I know that my equipment is working, or that these tests are accurate?" The best way to determine this and be sure of your results is to run a system suitability test.

Latest Release & Upcoming Events

In the upcoming weeks, we are proud to announce the release of our latest application note regarding concentration dependence in protein viscosity. In this app note, Dr. Stacey Elliott gathered viscosity data for Bovine Gamma Globulin (BgG) formulations over the full concentration range, including therapeutic levels ≥ 100 mg/mL, using the VROC®Initium. The solution buffer included sucrose which is a common additive to enhance stabilization during freeze-drying and storage. Relative viscosity versus concentration curves were fit with the Ross-Minton equation which is a frequently used analysis tool for protein formulations.

Different Ways to Measure Viscosity

Measuring viscosity dates back to as early as the 19th century. French physicist Jean Poiseuille discovered the concept of measuring viscosity by formulating the "mathematical expression for the flow rate for the laminar flow of fluids in circular tubes." Later on, this formulation was discovered by a German hydraulic engineer Gotthilf Hagen, which came to be known as the Hagen-Poiseuille equation (Britannica). Early measurements of viscosity focused primarily on the flow of blood. Measurements were conducted using the hemodynamometer that incorporated narrow tubes & glass capillaries in effort to measure the pressures in the arteries of horses and dogs (Sutera).
