Grips and Fixtures

The huge variety of materials and components tested means that both standard and custom grips and fixtures are used in biomedical testing.

Biological specimens can often be successfully tested with 2752 Series BioPuls submersible pneumatic grips used in conjunction with our BioBath for tests in saline and other liquids at body temperatures. Sutures, packaging, and adhesives can often be tested with our standard grip ranges. Nitinol wire can be successfully tested using pneumatic cord and yarn clamps.

Our range of compression anvils and flexure/bend fixtures can be used to measure the compressive and flexural strength of materials, components, and biological specimens.

Specialist fixturing is available for tests on dental materials, implants, needles, and medical devices. A range of component test plates for selected models allow the user to create their own custom solution for clamping components and medical devices.

Please refer to the dedicated section on biomedical/pharmaceutical fixtures for more details of suitable grips and fixtures.

Extensometry

Measurement of specimen strain can be very challenging in this application. Instron® non-contacting video extensometers can be used for testing delicate soft-tissue specimens even in a saline bath, providing contrasting marks can be applied to the specimen. Standard contacting devices can be used on rigid, semi rigid, and highly-extensible materials, such as elastomers.
