Fatigue testing machines are generally designed to identify the danger point or location of failure of a test piece of material that has been subjected to a series of stresses. This measures the durability or lifespan of a material or component, as well as the maximum load that it can withstand. After a sample is loaded into the fatigue tester, it is stressed until either a pre-determined number of cycles is reached or the material experiences failure. These tests can be performed with either constant amplitude or using servo hydraulic test machines.

- Modular, independent control of each heart valve station
- Simplicity in transfer of heart valve device from durability test instrument to pulse duplicator
- 2, 4, or 6-station unit
- Reliable – 10 year warranty on linear motors
... Read More | The DuraPulse™ Stent/Graft test (SGT) instrument extends the performance and reliability that ElectroForce SGTs have become known for over the past 20 years. Still utilizing proprietary high-bandwidth, low-distortion ElectroForce actuator technology to provide best-in-class performance, the The DuraPulse™ Stent/Graft test (SGT) instrument extends the performance and reliability that ElectroForce SGTs have become known for over the past 20 years. Still utilizing proprietary high-bandwidth, low-distortion ElectroForce actuator technology to provide best-in-class performance, the DuraPulse SGT incorporates a modular manifold design that allows the user to easily change out manifold and tube sets to optimize sample throughput for various stented device sizes.
Key Benefits: - Achieve highest strain and frequency combinations with closed-loop, symmetric dual-sided pulse
- Single test instrument can be optimized for device geometry and sample number with interchangeable manifold sets – 12, 8, 6, and 4 (bifurcated) mock vessel options
- Accommodates wide range of device diameters – 2 mm to 50 mm
- Conveniently measure tube strain across all tubes with optical micrometer positioning slide and 360° manifold rotation, and a tube scanning function that holds command levels and allows the laser to be repositioned during testing
- Select from 3 ID/OD Strain Calculation modes including Zero Strain or Zero Stress Conditions (as defined by ISO 25539-2)
- Automate test pressure control with optional Pressure Control Accessory (PCA)
- Clearly identify system operation state with System Status Indicator (SSI) lights
- Instrument reliability for years of use supported by industry leading 10 year actuator warranty
- Meets or exceeds international testing standards such as ISO 25539-2 and ASTM F2477
