Measuring viscosity at a single and arbitrary shear rate provides limited information which can be difficult to interpret. A much more thorough understanding of a formulation is obtained by measuring the shear rate dependence. In addition to the practical relevance of predicting the behavior during application or processing, the details of a non-Newtonian response reflect the molecular interactions and resulting microstructure at therapeutic levels. Even protein solutions at moderate concentrations can exhibit a Newtonian plateau followed by a shear thinning region illustrating the importance of non-hydrodynamic forces and degree of structure formation.
Last Wednesday, we hosted a new technical webinar where we focus on differentiating low viscosity fluids. If you were unable to attend or would like to access the recording and presentation again, you can now access the full recording.
We recently hosted a webinar where we went into details on viscosity measurements used as a guide when it comes to formulation development and the recording is now ready!
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.
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.
