Birefringence and viscosity measurements must be carried out at lower concentrations and at high accuracy if molecular theories are tested. For birefringence measurements a modulator is presented, which is easy to handle and enables measurements at briefringence effects nearly one decade lower than those at which measurements were possible until now. For viscosity measurements an entirely new apparatus is presented, with minimal drainage in a range of shear rates between 50 and 8000 (s−1) and a resolution and reproducibility of 0.1%.
