In our "Rheology Tools: Data Artifacts" webinar Principal Scientist, Dr. Stacey Elliott discusses the artifacts that may be observed in rectangular slit flows, including:
She shares what to look out for and how to handle it if it does occur.
Dr. Stacey Elliott obtained her extensive experience and rheological knowledge through her education at Carnegie Mellon University and Princeton as well as her experience at both Alcon and DuPont.
