Overview
The TA Instruments ElectroForce® Modular TestBench System is a precision-engineered, open-architecture platform designed for high-fidelity mechanical characterization of soft and compliant materials under controlled planar biaxial loading conditions. Leveraging electrodynamic actuation technology, the system delivers dynamic force control with sub-millisecond response time and high-frequency capability (up to 100 Hz standard, extendable with optional hardware), enabling rigorous evaluation of viscoelastic behavior, cyclic fatigue, stress relaxation, and creep compliance. Unlike monolithic testing frames, the modular architecture allows users to configure dual-axis actuators, environmental chambers, optical measurement subsystems, and custom fixtures—making it suitable for R&D laboratories requiring flexibility across biomaterials, hydrogels, elastomers, thin films, and cardiovascular tissue analogs. The system operates on closed-loop digital control firmware compliant with IEEE 1588 Precision Time Protocol standards, ensuring synchronization accuracy critical for multi-channel strain-force-time data acquisition.
Key Features
- Modular biaxial configuration supporting independent X- and Y-axis actuation with synchronized force control (200 N or 400 N maximum per axis)
- Integrated high-resolution digital video extensometry (DVE) with real-time sub-pixel edge detection and automated gauge length tracking—eliminating contact-based artifacts and enabling full-field strain mapping
- Electrodynamic linear motors delivering low-noise, oil-free operation with minimal thermal drift and long-term positional stability (±0.5 µm repeatability over 10⁶ cycles)
- Open API architecture supporting LabVIEW, MATLAB, Python, and .NET integration for custom test protocol development and automation
- Compliance with ISO 5840-3, ASTM F2058, and ISO 1798 for soft-tissue mechanical testing; compatible with third-party environmental enclosures (−40 °C to +150 °C, humidity-controlled)
- Modular load frame design with standardized mounting interfaces (ISO M6 and M8 tapped holes) for rapid reconfiguration between uniaxial, biaxial, and shear modes
Sample Compatibility & Compliance
The TestBench accommodates specimens ranging from 5 mm × 5 mm tissue coupons to 50 mm × 50 mm polymer membranes, with clamping options including pneumatic, screw-tightened, and vacuum-assisted grips. All configurations support GLP-compliant data integrity workflows: audit trails, electronic signatures, and 21 CFR Part 11–ready software modules are available via optional ElectroForce TestSuite™ v5.x. Mechanical calibration certificates traceable to NIST standards are provided with each system shipment. The platform meets essential requirements of ISO/IEC 17025 for accredited testing laboratories and supports validation documentation packages aligned with FDA Q5E and ICH guidelines for material comparability studies.
Software & Data Management
Control and analysis are performed using TA Instruments’ proprietary TestSuite™ software, which provides ISO 17025–aligned test method templates (e.g., biaxial tensile, inflation, constrained swelling), real-time FFT-based spectral analysis, and automated hysteresis loop quantification. Raw data is stored in HDF5 format with embedded metadata (timestamp, operator ID, calibration ID, environmental logs), ensuring FAIR (Findable, Accessible, Interoperable, Reusable) principles. Export options include CSV, MATLAB .mat, and MDF4 for compatibility with third-party post-processing tools such as DIAdem, Python SciPy, or ANSYS Workbench. Audit trail records capture all parameter changes, user logins, and report generations with immutable timestamps.
