Free Webinar: Good Viscosity Testing, now available to view on demand
Watch this upbeat, informative presentation if you want to:
- Get some quick tips for better Brookfield viscosity testing
- Understand how to choose the most appropriate test method for your products
- Learn some viscosity and rheology theory so you can confidently discuss your testing with management and co-workers
- Learn how to relate your viscosity results to product processing, stability and performance
The Brookfield viscometer is the worldwide workhorse for viscosity testing. However developing test methods and performing measurements that deliver repeatable and representative viscosity values can be a disconcerting experience, with the perplexed lab worker facing a bewildering array of instruments, accessories and test methods, every combination of which seems to deliver a different viscosity value for the same product.
Presented by the Centre founder, Neil Cunningham, Good Viscosity Testing is an easy, accessible guide to choosing and using viscosity testing methods. In addition to a wealth of practical tips participants will learn some basic viscosity and rheology theory concepts and will gain an insight into how viscosity results relate to how their products behave “in the real world”.
The webinar covers:
- What is viscosity and why does it matter?
- Non-Newtonian liquids
- How do we measure viscosity?: The ubiquitous Brookfield viscometer.
- Understanding the models: LV or RV? DV1, DV2 or DV3??
- So many spindles!: Discs, T-bars, small sample adapters, UL adapters..
- Guidelines for a good viscosity test:
- Choosing a speed: 5 RPM? 50 RPM? Somewhere in-between?
- Temperature and its effect on viscosity
- Sample handling and conditioning
- What is the torque percentage and why does it matter?
- My viscosity keeps changing!! When to take the viscosity reading.
- Measuring soft-solids: creams, gels, pastes, waxes
- Getting serious about viscosity: Using shear rate and shear stress for viscosity profiling
The presentation will last 30 minutes and is followed by a Q&A session which enables you to ask any questions you like relating to the webinar content or your own particular products, applications and issues.
