Discovery HR x0
Hybrid Rheometers Series
Manufacturer
TA Instruments |
Discovery HR x0 is a series of new-generation hybrid rheometers that deliver precise rheological measurements for a wide set of modes: controlled stress, strain or rate; steady shear or oscillation; rotational, tensile, compressive or extensional deformation.
Superior performance. A rheology data accuracy, first of all, depends on the fundamental measurements of Torque (stress) and Displacement (strain). Compared to existent analogues, Discovery HR x0 has the advantages:
- the highest torque sensitivity – due to the patented Magnetic Bearing, decreasing friction by >70% (vs. air bearings), enabling accurate low-stress measurements such as yield stress and zero-shear viscosity;
- the best displacement resolution – due to the patented Optical Encoder Dual Reader, enabling the most precise measurements of shear rate and small amplitude oscillatory strain.
Ease of Use. Discovery HR x0 is designed to enable every operator to get the most accurate rheology data. Convenient features such as integrated sample lighting and an intuitive touchscreen make sample loading easy and repeatable. TRIOS Express software has test methods are streamlined in for routine testing, while TRIOS Unlimited allows complete customization for advanced characterization.
Versatility. A wide range of accessories is available for Discovery HR x0 allowing the rheometers to be configured for various experimental needs. SmartSwapTM geometries and accessories are quickly installed and automatically identified, that is actual for labs supporting a growing range of materials and testing requirements. A possibility to operate in a glovebox provides reliable rheological data of atmosphere sensitive samples.
- Support all widespread types of measurement geometries: plate/plate, cone/plate, concentric cylinders
- Wide ranges of a mechanical stress and a deformation rate
- Rheological measurements with the Fourier transform
- Tests of materials with various chemical and physical properties with an aggregate state from liquid to solid one
- Dynamic Mechanical Analysis (tension, compression, torsion, bending of a bar with free and fixed end points)
- Tribology analysis
- Dielectric analysis
- Measurement under action on a sample of different controlled conditions: temperature, pressure, electrical current, magnetic field, humidity, UV radiation
- Possibility of joint operation with the Raman spectrometer, microscope, Small Angle Light Scattering system
