The Absorbable Bone-connecting Plates Four-point Bending Tester is a specialized testing machine designed to evaluate the mechanical performance of absorbable bone plates under bending loads. It uses a four-point bending setup to measure parameters such as bending strength, stiffness, and deformation, simulating physiological forces experienced in orthopedic applications. This device is essential for assessing the durability and structural integrity of biodegradable bone fixation implants before clinical use.

Standard

(1)ASTM F2119: Standard test method for constant load testing of bioabsorbable screws and washers, applicable to bending performance evaluation.

(2)ISO 10993-1: Biological evaluation of medical devices, ensuring compatibility with biodegradable material testing.

(3)YY/T 0342: Chinese standard for bending strength and stiffness testing of metallic bone plates (adapted for bioabsorbable materials).

Product Advantages

(1)Biodegradable Material Expertise:

Optimized for polymers (PLA, PGA) and composites, with adjustable test parameters to accommodate degradation-induced property changes.

Environmental control options (37°C ± 2°C, pH-regulated media) for simulating in-vivo conditions.

(2)Precision Four-Point Bending:

Electromagnetic load frame with ±0.1% force accuracy, ensuring compliance with ASTM F2119’s resolution requirements.

Adjustable span ratios (10:1 to 20:1) for tailored stress distribution analysis.

(3)Advanced Data Acquisition:

Real-time monitoring of force, displacement, and bending modulus with 5000Hz sampling rate.

Automatic calculation of key parameters: bending strength (MPa), flexural modulus (GPa), and strain-at-break.

(4)User-Centric Design:

Intuitive software with preloaded SOPs for ASTM F2119 and ISO 10993-1 compliance.

Multi-language interface (English/Chinese/Spanish) and exportable reports (PDF/Excel/CSV).

(5)Durability & Safety:

Corrosion-resistant components and overload protection system for long-term reliability.

Low-noise operation (<65 dB) suitable for laboratory environments.

Product Features

(1)Load Capacity: 5 kN (axial) / 250 Nm (torsional).

(2)Force Resolution: 0.001 N (axial) / 0.0001 Nm (torsional).

(3)Displacement Accuracy: ±0.1 μm.

(4)Testing Modes:

Bending stiffness (ASTM F2119).

Bending strength (YY/T 0342 adaptation).

Creep testing (constant load over time).

(5)Software Suite:

Customizable test profiles with automated pass/fail criteria.

21 CFR Part 11 compliance for audit trails and electronic signatures.

(6)Calibration: NIST-traceable certification included, with annual recalibration available.
