"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.

How Viscosity Shapes the Earth

Not many people besides rheologist and scientist think much about viscosity, but it plays a very important roll in geology and geography. Check out this NASA article and next time you look at the landscape you might be thinking about viscosity.

A Robot Be Doing Your Job In 5 Years

We have all read this click bait title many times over. 

Yes, we are at the dawn of the autonomous revolution and ultimately, some jobs will be replaced by robots. The good news is that this revolution is going to accelerate science and technology at a rapid pace. The companies and individuals who invest and embrace automation will have a large competitive advantage over those who stick to traditional techniques.

Visualizing Viscosity

One of the challenges of creating monoclonal antibody (mAb) injectable drugs is optimizing formulation. A good formulation has to have a high concentration of stable mAb’s for high efficacy. There are a variety of factors that can affect stability of these mAb’s, temperature, shear forces, pH, and even concentration. When proteins become, unstable and denature they can increase the viscosity of your formulation. Using a simple modified parallel plate demonstration, we can visualize why denatured proteins increase viscosity.
