General Information


Rheometer with in situ FTIR


With a rheometer the steady state and time dependent viscoelastic properties of a material can be studied as a function of stress and/or strain. This equipment couples a rheometer with an in situ attenuated total reflectance Fourier transform infrared spectrometer (ATR-FTIR) which enables a simultaneous study of chemical information with rheological properties over a temperature range from ambient to 400 °C. Additionally, this equipment has a controlled test chamber with solid dynamic mechanical analysis (DMA) clamps for testing the viscoelastic properties of thin films from -150 °C to 600 °C.
