Info

8 LabRheo Based on Microsoft’s .NET framework, this software is fully network capable and allows parameter manipulation, measurement and evaluation of all the rheometer’s functions. Functionality Evaluation Ease of use, covering a wide range of application needs, this software offers an all in one solution tool. • Use of Microsoft ACCESS Database • Freely configurable display of data tables and graphics • Automated acquisition of all test instrument data • On-line help, self-diagnostic and info fields to help the user • Open platform for user specified fields and filters for measurements • Managed access for more data security • Calculations for round hole and slit capillaries • Corrections with Rabinowitsch-Weissenberg, Bagley (linear/non-linear), Mooney, Hagenbach, Gleissle • Approximation of flow curves according to following models: Ostwald-De Waele (Power law), Carreau-Winter, Yasuda, Sabia, Muenstedt and Cross • Elongation viscosity with Cogswell • Additional evaluation tools such as Non Newtonian Index calculation (NNI), thermal degradation, relaxation, wall slip and ramp functions • Normal stress • Temperature Shift o Creation of master curves at different temperatures o Determination of model coefficients for the master curve o Approximation of the master curve according to Carreau-Winter and Cross o Calculation of shift factors according to WLF and Arrhenius
