Rheometers
  • TA Instruments DHR-2 rheometer
  • Brookfield viscometers
  • Custom-built pipe rheometers
  • Flow imaging and velocity profiling combined with rotational and pipe rheometry
Accessories
  • Wide selection of measurement geometries: parallel plates, cone-and-plate and concentric cylinder geometries with various surface finishes (smooth, sandblasted, crosshatched, serrated). Vane-in-cup geometries are available 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 (OCT) and digital microscopy
  • Peltier temperature control: parallel plates & cone-and-plate: -40 to 200 °C, concentric cylinder & vane-in-cup: -20 to 150 °C, rheo-optics: -20 to 100 °C
  • 3D-printed measurement geometries: possibility to design and manufacture customized measurement geometries using different 3D printing techniques
  • Modular, customizable pipe rheometers: pressure loss and viscosity measurements on liquids, suspensions and foams in various pipe flow geometries
  • Flow imaging and velocity profiling: analysis of sample microstructure, velocity profile and wall slip in rotational and pipe rheometer measurements using optical coherence tomography (OCT), ultrasound velocity profiling (UVP) and high-speed video imaging (HSVI)

  HIGHLIGHTS
Carl Klason Rheology Awardee 2026: Mats Larsson
We are extremely pleased to announce Mats Larsson as the recipient of the 2026 Carl Klason Rheology Award. The announcement was made by the NRS President Olli-Ville Laukkanen at the RheoMAXESS/AIDA workshop at LINXS - Institute of advanced Neutron and X-ray Science.

Award Citation: "For pioneering contributions to rheological research and instrumentation that have bridged academic research and industrial application, and for his enduring leadership in advancing and promoting rheology in the Nordic countries through innovation, education and collaboration."

Mats is one of the most well-known faces in the Nordic rheology community, having worked in the field of rheology since early 1980s. He is the first author of the most cited paper ever published in the Annual Transactions of the Nordic Rheology Society (currently 285 citations), titled "Suspension stability; why particle size, zeta potential and rheology are important". Mats has been heavily involved in the development of novel rheological measurement techniques over the decades, and he has also made an exceptional effort in popularizing rheology in the Nordic countries and beyond.

Mats is invited to give an award lecture at the Nordic Rheology Conference & Mechanics of Time-Dependent Materials Conference 2026 in Lund in August.

Let's congratulate Mats for this great accolade! 👏
