Rheometers
  • TA Instruments DHR-2
  • Brookfield LVDV-II+Pro Extra viscometer
  • Custom-built pipe rheometers
Accessories
  • Wide selection of measurement geometries: various parallel plate, cone-plate and concentric cylinder geometries, as well as vane-in-cup geometries for the rheological characterization of samples exhibiting wall slip, large particles and/or sensitive microstructure
  • Rheo-optics: transparent measurement geometries for simultaneous rheological characterization and imaging of sample's microstructure with optical coherence tomography and optical microscopy
  • 3D-printed measurement geometries: possibility to design and manufacture customized measurement geometries using different 3D printing techniques
  • Modular pipe rheometers: pressure loss and viscosity measurements on liquids, suspensions and foams in various flow geometries (straight pipes, elbow pipes, orifice plates, etc.) with simultaneous flow imaging and wall slip analysis

  HIGHLIGHTS

Memorable NRC2024 in Stavanger
The 33rd Nordic Rheology Conference gathered 75 rheology enthusiasts in Stavanger on May 29-31, 2024. This was the third time that Nordic Rheology Conference was organized in Stavanger, the previous times being in 1996 and 2007. The conference was a great success with insightful scientific presentations, lively discussions and unforgettable social events.
A big thank you to everyone who attended the conference and made it a memorable and enjoyable event for all of us. In particular, we would like to thank the NRC2024 plenary speakers for their exceptional scientific contribution to the conference: Pier Luca Maffettone, Helen Wilson, John Hinch, Manfred Wilhelm and Jan Schäffer.
We would also like to thank the conference sponsors and exhibitors for their financial contribution to the organization of the conference and for showcasing their products and services at the conference: Tine, TA Instruments, Netzsch, Oleinitec, Gammadata Instrument & Thermo Fisher Scientific, Houm, Reokonsa AB and Colloids and Interfaces.
Last but certainly not least, we would like to extend our sincere gratitude to the NRC2024 organizing committee: Conference Chair A. H. Rabenjamanantsoa, Arild Saasen, Vanessa Grace Ochon Booc, Linda Natalie Borho, Guro Mette Viker Bråthen and Kjetil Tjåland.
