Testing of implant materials and laboratory instruments

Testing system & equipment

The inspekt blue 20 kN universal testing machine with squeezing device enables mechanical tests on biomaterials and laboratory instruments. This includes compressive strength tests on bone cements and squeeze-out tests from syringes. These synthetic replacement materials must exhibit high strength as well as resistance to fracture and deformation. The test results also provide important information about the material composition and therefore the load-bearing capacity of the end product.

Testing of bone cements (compression tests)

• Objective: Quality control of synthetic bone replacement materials for medical technology.
• Field of application:
  • Orthopaedics
  • trauma surgery
  • neurosurgery
  • Oral and maxillofacial surgery
  • Dentistry

Test procedure

• Sample preparation: Small cement samples are cast and hardened.
• Compression test: The specimens are clamped in the universal testing machine and subjected to a constantly increasing pressure of up to 20 kN.
• Evaluation: The pressure curve provides information on the material composition and load-bearing capacity.

Characteristics:

• Practical test specifications
• Quick & easy measurement of different specimens
• Optimization of material composition & applicability

Squeeze-out tests on syringes

• Objective: To determine the optimum consistency and applicability of bone cement in syringes.
• Background: Bone cement is supplied pre-filled in syringes. It only hardens when it comes into contact with body fluid. The viscous consistency must be applied through cannulas of different diameters.

Test procedure

• Clamping the syringes with bone cement in the testing machine.
• Squeeze-out test: The material is squeezed through cannulas with varying diameters via the squeeze-out device.
• It is tested which combination of cannula diameter and cement consistency offers the best user-friendliness.
• Result: Optimization of applicability for safe & easy use in minimally invasive surgery.

Conclusion

With the inspekt blue 20 kN universal testing machine, the strength and applicability of implant materials and laboratory instruments can be precisely analyzed - an important contribution to patient safety and product optimization in medical technology.
