Testing and validation of biomaterials used in medical implants and devices is crucial to assure performance and durability. Triaxial testing of tissues adds a unique shear component to examination of mechanical behaviour. For this, Instron provides a unique solution through its high precision and modular LF-XXX Triaxial Test System. This system is ideally designed for testing of a wide range of materials ranging from polymers, rubbers to tissues such as brain, stomach and thus is an ideal instrument for research and development. The LF-XXX system is well- suited to perform triaxial testing on animal/human or other tissue samples which makes it an attractive instrument for tissue engineering, mechanobiology and regenerative medicine research labs.
