Webinar 1: Better Rheological Results—What to Do Before Pressing the Start Button?
Rheological samples are often delicate, sensitive, and need to be handled with care. Simple handling mistakes or test method errors can result in unreliable or unreproducible rheological measurements, setting you back in both time and money. Watch this webinar to review how to avoid the common pitfalls in preparing for rheological tests. It covers the critical steps that must take place before you even press ‘start’ on your rheometer. Webinar 2: Better Rheological Results – Select the Right Measuring Geometry Choosing the right measuring system is crucial for reliable and reproducible rheological data. Learn how to select the optimal geometry according to your type of rheometer, test conditions and sample properties. Watch this webinar on selecting the right measuring tool and procedure for the job.

Broadening Measurements with Simultaneous Rheology and DEA
A rheometer provides bulk information from a sample, while a DEA (dielectric analyzer) gives additional information about the details on molecular level. The Thermo Scientific HAAKE MARS Rheometer, with an integrated DEA sensor, allows simultaneous collection of rheological and DEA data on the same sample at the same time, which can be connected with the sample history or pretreatment. This approach saves time and money with shorter time for preparation and analysis.
