rheometer

Product catalog summary

Overview: The VISCO-ELASTOGRAPH is an oscillating rotational rheometer designed for the dynamic-mechanical analysis (DMA) and characterization of viscoelastic properties in rubber compounds. It is certified according to DIN EN ISO 9001:2000 standards and provides highly accurate and repeatable measurements.

Applications:

Research & Development: Rheological characterization of raw polymers and blends, focusing on molecular weights and distributions.
Production: Quick quality control release with feedback on viscoelastic properties.
Incoming Quality Control: Testing raw materials against required specifications.

Test Methods:

Amplitude Sweep: Measures stress by oscillating the lower half of the chamber between 0.01 and 20°.
Variable Time: Measures complex modulus and viscosity over time at constant strain amplitude and frequency.
Frequency Sweep: User-defined sinusoidal deformation between 0.01 and 33 Hz to measure torque, complex modulus, and viscosity.
Temperature Sweep: Internal temperature control allows defined temperature steps.

Software and Operation: The VISCO-ELASTOGRAPH is operated using GurWebRheo software, offering various data viewing options such as frequency and amplitude sweeps, relaxation tests, and dynamic viscosity measurements. It features a user-friendly design with a touch screen for service functions and real-time data display.
