New Add-on for Capillary Rheometer – Effective determination of normal stress at high shear rates
Channel: GOETTFERTtv
Date: 2023-08-29

The "Normal Stress Die" is designed to simultaneously measure steady state shear viscosity and first normal stress difference of viscoelastic liquids via capillary rheometer.

The new slit-radial die which was developed in cooperation with the "Institute for Technical and Polymer Chemistry" (Working Group of Prof. Wilhelm) of the KIT in Karlsruhe, serves as an Add-on for polymer differentiation for the updated series of Capillary Rheometers and as a modular retrofit for existing instruments.
