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
NanoLund/RheoMAXESS Workshop on Scattering for Soft Matter: static and in flow
Learn more about scattering for soft matter, including a hands-on session in the afternoon!

🗓️ When: 29 September, 2025, 09:00-17:00
📍 Where: LINXS (The Loop, Rydbergs torg 4, 224 84)
👨‍🏫 Organisers: NanoLund/RheoMAXESS theme at LINXS

This workshop will cover neutron and synchrotron X-ray techniques to probe soft matter, including small angle scattering, reflectivity and imaging. We will describe sample environments that allow both static measurements and time-resolved data collection, including combined measurements enabling simultaneous data collection with techniques such as rheology, dynamic mechanical analysis, polarised light imaging and flow in microchannels.

In the afternoon data analysis session, we will present typical analysis software and allow participants to try data fitting with their own, or supplied data (see survey during registration)
