Testing and validation of biomaterials used in medical implants and devices is crucial to assure performance and durability. In case of artificial tissues/live tissues, biaxial testing is necessary to negate the effects of mechanical anisotropy inherent in these materials. For this, Instron provides a unique solution through its high precision and modular BLF-XXX Planar Biaxial System. This system is ideally designed for testing of a wide range of materials ranging from polymers, rubbers to animal skin and thus is an ideal instrument for industrial research and development. The BLF-XXX system is well- suited to perform mechanical testing on animal/human or other tissue samples which makes it an attractive instrument for tissue engineering, mechanobiology and regenerative medicine research labs.
