Shanghai Jituo Technology provides rheology testing services. Rheology testing is used for measuring material viscosity, storage modulus, loss modulus, and loss factor, and can perform capillary rheology and rotational rheology tests.
Principle of Rotational Rheometer
The sample is subjected to program-controlled temperature and applied with single-frequency or multi-frequency oscillatory force to determine the relationship of storage modulus, loss modulus, and loss factor with temperature, time, and force frequency.
Instrument Model and Technical Parameters
- Instrument Model: Anton Paar MCR302
- Technical Parameters:
- Temperature range: -15 to 350°C
- Shear rate: 0.001 to 1000 1/s
- Temperature accuracy: ±0.1°C
- Heating rate: 0.1 to 50°C/min
Sample Submission Requirements and Packaging
- Fluid samples: 2–10 mL in a plastic centrifuge tube.
- Samples must be free of low-boiling solvents or water.
- Samples must not crack, explode, volatilize, or produce highly toxic gases within the testing temperature range, as this may cause irreversible damage to the instrument.
