Why you need to measure a full range of shear rates.

A lot of my customers have admitted to measuring viscosity at a shear rate of 1,000 1/s when it comes to formulating various types of drugs including injectables. However, from our recent in-depth analysis of various salt concentrations added to proteins, our results further confirmed why you are not getting your full spectrum when it comes to measuring your proteins at just one and a low shear rate of 1,000 1/s.

  1. Viscosity measurement at wide shear rate range (low to high shear rates) probes Protein to protein interaction and set a better course to formulation optimization of protein therapeutics.    
  2. Accurate injectability estimation requires high shear rate viscosity measurement.  Need to measure viscosity not only at 1000 1/s but also at 100000 1/s.

How To Select Your Desired Shear Rate

One of the most commonly asked questions from our customers is the topic of shear rates and what to expect when dealing with various applications. Now most of you have a general idea on what shear rate means, but we want to take it one step further and illustrate several key components when dealing with shear rates.

"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.

The Explanation of Rsquared Values on RheoSense Viscometer Software

I recently got a pretty challenging question from one of my customers who mentioned that their professor had given a lecture back in undergrad about r-squared values not being a trustworthy method to determine how close your data is to the regression line. Now I don't want to undermine the professor's argument as I understand where such opinions come from.

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.
