Discovery HR 10

Sensitivity

Measure the lowest stresses and smallest sample volumes with revolutionary torque sensitivity
Unrivaled low torque sensitivity empowers you to measure lower viscosities and weaker intermolecular structures while using lower sample volumes.

All Discovery Hybrid Rheometers feature TA’s patented Magnetic Thrust Bearing which reduces basic system friction by 70% compared to traditional designs. By eliminating the contributions of high pressure, turbulent air flow from the measurement system, lower torques can be measured reliably and accurately.

The unparalleled sensitivity of the magnetic thrust bearing is coupled with the NEW improved Advanced Drag Cup Motor. Enhanced torque precision increases the accuracy of every measurement, especially at low torques.

Dynamic Measurements

Report G’ and G” with confidence
The storage and loss modulus, G’ and G”, are two of the most insightful measurements provided by any rheometer. The HR 10’s Advanced Drag Cup Motor is optimized for accuracy in dynamic measurements. The low-mass and -radius design reduces system inertia by up to 80% compared to DC motors, minimizing corrections to oscillation data, especially at higher measurement frequencies. The result is a wider range of accurate measurement frequencies, material types, and experimental designs.

Strain and Stress Control

The measurement you want: Advanced Strain and Stress Control
The Discovery Hybrid Rheometer performs the experiment you want, whether stress-controlled, strain-controlled, or both. State-of-the-art high-speed electronics and the responsive Advanced Drag Cup Motor provide the fastest transient responses and accurate control in any type of deformation. Optional Direct Strain oscillation provides real-time strain control at every point of the oscillatory measurement.

Reliability

The Discovery Hybrid Rheometers are designed with sensitivity to measure the softest materials, and are constructed to be rugged enough to handle the stiffest materials and toughest users.

A rigid cast aluminum frame and rugged linear ball slide provide more than 60% greater axial and torsional stiffness than other designs and permit gap position resolution of 0.02 µm.

Two high-stiffness radial bearings stabilize the system from side loads exerted by samples or operators while the Optical Encoder Dual Reader further cancels displacement measurement drift associated with testing very stiff samples over long times.

The Advanced Drag Cup Motor provides stable control and measurement even when operating under extreme conditions. Active and passive thermal systems manage heat and account for system temperature, guaranteeing measurement accuracy under all test conditions.

These innovations provide the most accurate and sensitive measurement, under even the most extreme experimental conditions.

Advanced Technology

True Position Sensor
The DHR includes the patented True Position Sensor (TPS) for true gap accuracy. The TPS is a high-resolution linear position sensor that measures and compensates for the effects of thermal expansion in real time. Unlike competitive devices, the TPS eliminates errors associated with thermal expansion without the need for special high inertia iron core geometries and environmental systems. The TPS works with all Smart Swap™ geometries and Smart Swap™ environmental systems.
(US Pat #10,161,843)
Normal Force Rebalance Transducer (FRT)
The Force Rebalance Transducer is the premier technology for normal force measurements. This active, non-compliant device accurately measures normal and axial forces without deflection. Competitive capacitive or strain gauge sensors rely on physical movement of the device to sense a force, resulting in measurement error. The FRT provides the most accurate normal force measurement by driving the linear motor to maintain zero deflection at all times and conditions.

Sample handling

The NEW Discovery Hybrid Rheometer is your invisible partner in the lab, reducing the time from question to insight.

Load samples with confidence and ease

The Discovery Hybrid Rheometer is designed by rheometer users to make sample loading faster, easier, and improve measurement precision for every operator.
