When the assumptions used to perform the viscosity calculation are violated, the value provided by the instrument is flawed. These errors are commonly referred to as artifacts. We share the artifacts that may be observed in rectangular slit flows, what to look out for and how to handle it if it does occur.
We brought together a panel of speakers for from industry and academia to facilitate the discussion of rheology fundamentals with a focus on viscosity applications. Our speakers shared their rheology expertise, building awareness of the significance of viscosity across their industries.
Our team closed our 2020 demonstrating how easy it is to use our portable microVISC™ viscometer. Walking through each step from choosing the right chip for your sample to creating proper cleaning protocols.
We demystify rheology tool selection, discussing geometry selection for commonly used rheometers and viscometers as well as how to choose the right flow channel for your favorite VROC® instrument.
We share the benefits of characterizing true viscosity, discussing the data, calculations and material characterization of your samples provided with RheoSense sample testing services on our VROC® powered viscometers.
We discuss the benefits of measuring and analyzing dilute solution viscosity for macromolecules in organic solvents and aqueous solutions.
In this webinar we show how we used automated viscosity measurements to monitor the ageing of concentrated bovine gamma globulin in phosphate buffered saline solutions with different excipients.
We explain the differences between Newtonian and non-Newtonian fluids and the fundamentals on establishing the viscosity fingerprint of materials using real application examples.
We address how the rheological behavior of both Newtonian and non-Newtonian therapeutics can help determine injectability in the initial stages of product development.
In our educational webinar, we explain how to use shear thinning analysis to assess temperature, concentration, and protein excipient levels
The viscosity of blood influences at least three variables: its ability to clot, perfuse tissue, and vascular resistance. An abnormally high blood viscosity can be an indicator of underlying health issues and a predictor of adverse events such as COVID19, Diabetes, & more.
This is our back to basics webinar discussing the different types of viscosities.
We discuss the origins of non-Newtonian behavior and what viscosity data on these systems are telling you.
We review the basic principles behind viscosity measurements. Our discussion will clarify the terminology and many misconceptions about measuring viscosity.
Learn what viscosity is, why you need to measure it with cannabis, and how to measure it by downloading this webinar!
We go step-by-step through the process of calculating the injection force from actual viscosity data.
We review the non-Newtonian response of protein solutions under steady shear and discuss options for interpretation.
We explain sample differentiation ability of microfluidics based instrumentation with measurement protocol tips.
We explain how to select the right shear rates and design your experiments to get the most out of your viscosity measurements.
We discuss the preparation and viscosity measurement of nylon 66 in formic acid, but the concepts can be applied to other polymer/solvent systems.
We illustrate how defining delivery options and measuring viscosity early in the formulation process will ensure that the appropriate excipients are added to the buffer and the desired result is achieved.
Featuring University of Texas at Austin, we cover why viscosity reduction occurs and how to detect the presence through shear dependent rheology methods.
Designed to be a more sensitive and progressing viscometer, VROC® intium is packed with intelligence and intuition that enables the end users to measure not just viscosity measurements but to use viscosity to provide insight into their product performance and application.
This webinar will show a brief demonstration of the m-VROC® viscometer. Learn how to use small sample sizes and see the different configurations that can be plugged with the viscometer!
We cover the significance of Intrinsic Viscosity and how to apply such measurements to your work!
This webinar will review the standard features of VROC® initium and present advanced measurement features for.
This webinar will be helpful for people curious about viscosity (like us!), those who are just starting to use viscosity for their work or want to refresh their knowledge about basic concepts of viscosity!
This webinar introduces RheoSense's automatic, high throughput viscometer, VROC initium.
We demonstrate our technology capability to overcome some of the challenges encountered by conventional methods to measure viscosity when dealing with blood samples.
We trace the historical development of viscosity and viscometers; starting with the fundamental principles established by Sir Isaac Newton and leading up to modern-day viscometry methods.
We demonstrate how VROC® technology can be used to study applications such as protein structure (i.e. denaturation and folding) at a fraction of the sample volume required by conventional technologies.
This webinar was our first formal product preview for the automatic, high throughput viscometer, VROC initium.
A Tool to Determine Molecular Size & Structure Through Viscosity Measurements.
We measured the viscosity of various holiday beverages.
