Condition: like new (used), TA Instruments Discovery HR-1 – Hybrid Rheometer with Temperature Chamber Technical description of the device Manufacturer: TA Instruments, USA Model: Discovery HR-1 Series: Discovery Hybrid Rheometer Device type: Rotational-oscillatory rheometer Temperature system: Two-wing heating chamber, possibly an ETC (Environmental Test Chamber) Technical characteristics The TA Instruments Discovery HR-1 is an advanced hybrid rheometer designed for the precise investigation of the rheological properties of liquids, semi-finished products, polymers, pastes, gels, and viscoelastic materials. The device enables measurements in controlled stress mode, controlled shear rate mode, and oscillatory testing. The rheometer's design utilizes a precise drive system, a torque measurement system, and a gap control system. Technical parameters – Discovery HR-1 The following values are approximate catalog parameters for the HR-1 model and require confirmation for a specific device version. Parameter | Value ----- | ----- Type of measurement | Rotational and oscillatory Minimum oscillatory torque | approx. 0.5 nNm Minimum rotational torque | approx. 10 nNm Maximum torque | 150 mNm Angular speed range | up to 300 rad/s Oscillatory frequency range | up to 100 Hz Angular displacement resolution | approx. 10 nrad Rsdpfex E Sm Hsx Airsch Gap control | Automatic Control modes | Stress, shear rate, oscillation Computer control | TA Instruments TRIOS software Temperature control system The device shown in the pictures is equipped with a two-part heating system that opens to the sides. The chamber enables rheological measurements to be carried out under controlled temperature conditions. System characteristics: * Two-wing design of the heating chamber. * Electric heating system. * Temperature control of the sample. * Possibility of conducting temperature studies. * Thermally insulated chamber elements. * Connections for the temperature control system. If the use of an ETC chamber is confirmed, the typical temperature range may be approximately -160°C to +600°C, depending on the configuration, cooling system, and accessories used. This range is not confirmed for the offered unit. Available research methods Rotational studies: * Viscosity measurement as a function of shear rate. * Determination of flow curves. * Study of the yield point. * Analysis of the behavior of non-Newtonian materials. Oscillatory studies: * Measurement of the storage modulus G'. * Measurement of the loss modulus G''. * Analysis of the loss tangent tan δ. * Frequency tests. * Amplitude tests. * Analysis of structural transitions of materials. Time and temperature studies: * Creep and recovery tests. * Stress relaxation. * Thermal stability studies. * Analysis of changes in rheological properties as a function of temperature and time. Configuration of the offered device Based on the photographic documentation, the set includes: 1. TA Instruments Discovery HR1 rheometer 2. Two-wing temperature chamber. 3. Accessories visible in the pictures 4. PC and software The device is a professional measurement platform designed for advanced rheological analyses in industrial and scientific laboratories.
