The Polymer Characterization Facility is maintained by the CEMS Polymer Group, but is available to researchers campus wide, and also to industrial clients (IPRIME Industrial Partners get a significant discount). Assistance or collaboration is available for testing, training, and interpretation of results. For more information, contact David Giles at (612) 625-0880 or giles@cems.umn.edu . The Rheology Lab is a major part of the Polymer Characterization Facility. See also: The Rheology Short Course .
