Planar Biaxial Bio Tester
The Planar Biaxial Bio Tester is a compact, benchtop testing machine designed for the biaxial mechanical testing of soft tissues and biomaterials. Engineered for accurate multiaxial stress-strain analysis, it features two orthogonal, servo-controlled actuators that apply tension in perpendicular directions — essential for evaluating anisotropic behavior, hyperelasticity, and viscoelastic properties of delicate biological samples.
This advanced system integrates real-time feedback control, high-resolution displacement tracking, and optional temperature-controlled fluid chambers to simulate physiological environments. Compatible with Digital Image Correlation (DIC) and suitable for custom specimen geometries, the system is ideal for biomechanical research, medical device validation, tissue engineering, and academic studies requiring precision and repeatability.

Key Features of the Simple Column Low Force Test System
- Dual-Axis Servo-Controlled Loading: The system uses two independently controlled actuators placed at 90°, enabling true biaxial tensile loading. This allows simulation of complex multiaxial stress states, crucial for testing biological soft tissues and hyperelastic materials.
- High-Precision Force and Displacement Measurement: Integrated load cells and digital encoders provide force feedback and displacement resolution as fine as 0.1 µm, ensuring exceptional accuracy across both low and high strain ranges.
- Real-Time Digital Feedback Control: A closed-loop control system offers real-time adjustments to applied load and displacement. This ensures test reliability and repeatability, especially during fatigue and cyclic testing on sensitive specimens.
- Programmable Software Platform: The system’s PC-based software allows users to define and automate complex test profiles including ramp, sine, triangle, hold, or custom waveforms. Built-in logging and graphing features make data analysis efficient and intuitive.
- Quick-Change Grip and Fixture Design: Equipped with modular grips, the system enables fast setup changes. Custom grip options ensure secure mounting of fragile or elastic specimens, reducing risk of damage or slippage during testing.
- Open-Frame Configuration for DIC Compatibility: The open structure supports integration with Digital Image Correlation (DIC) systems for non-contact, full-field strain tracking, ideal for anisotropic deformation studies in biomedical research.
- Temperature-Controlled Testing Environment (Optional)
An optional transparent bath chamber maintains test environments between 5°C to 45°C, making it possible to test biological specimens under hydrated, temperature-regulated conditions that simulate in vivo behavior. - Supports Multiple Sample Geometries: Designed to test rectangular, circular, and custom-shaped specimens, this flexibility supports a wide range of research and clinical applications.
- Compact and Ergonomic Design: The benchtop configuration saves space while offering high performance, making it suitable for laboratories with limited space and advanced research needs.
- Standards-Compliant and Research Ready: Fully aligned with international testing protocols such as ASTM F2150 and ISO 14243, ensuring reliable, publication-grade data for academic or industrial research.
