NanoIndenter XP microprobe system

The NanoIndenter XP Mechanical Properties Microprobe System is an automated system for instrumented indentation of materials.

The system consists of a controlled indentation tip with force-controlled vertical displacement. During the indentation, force and displacement versus time are recorded. The specimen is mounted on a precision-controlled x-y stage to precisely position the indentation.

For hard materials, the standard outputs are hardness and elastic modulus. You can also use it for soft tissues with custom data reduction algorithms.

TestWorks 4 software controls the system, allowing great flexibility in design and operating custom testing protocols. The system has a lateral force option for scratch testing, a continuous stiffness module for continuous stiffness monitoring, and a higher precision test head.

Hard materials

Well-developed methods for characterizing material properties of small material volumes:

  • Elastic modulus and hardness of metals, ceramics, and other hard materials.

  • Viscoelastic properties of materials using harmonic loading (storage modulus, loss modulus), constant load (creep response), or constant displacement (relaxation response).

  • Scratch testing to determine film adhesion, coefficient of friction, and variation of properties with depth.

Soft tissues

  • Non-penetrating indentation to determine elastic and viscoelastic properties of soft tissues.
