The CETR-Apex from Bruker is an indenter and scratch tester with industry-leading sensitivity, unmatched performance and versatility, and separate modules for micro- and nanoscale testing.
Nano Module NH
With the progress of nanotechnology and development of thin films (solar cells, cvd, pvd, DLC, MEMS, etc.) nano-mechanical tests have become standard. They improve on the traditional tests by being done at low loads and shallow depths with very sharp tips, high spatial resolution and in-situ precise load-displacement data.
Nano Indentation - Single/multiple indents per the ISO 14577 to measure hardness, Young’s modulus, tensile and von Mises stresses, contact stiffness, etc. of thin films, thick coatings and bulk material.
Nano Scratch at constant, increasing and user-defined programmable load to evaluate scratch hardness and scratch adhesion of thin films, thick coatings and bulk materials.
Dynamic Indentation (with vibrating tip) to measure depth-dependent loss and storage moduli.

Micro Module NH
Micro-mechanical tests have been used to measure mechanical properties of coatings or bulk materials. Instrumented micro-mechanical test improves on the traditional ones by providing in-situ load-displacement data and by using advanced signals like acoustic emission, ECR, friction, etc. for more comprehensive characterization.
Instrumented Micro Indentation - per the ISO 14577 on macro-scale (for loads greater than 2 N) and micro-scale (loads under 2 N) to calculate hardness, Young’s modulus, tensile and von Mises stresses, contact stiffness, etc. of coatings and bulk materials.
Traditional Vickers and Knoop micro-hardness per the ASTM E384-99.
Micro Scratch at constant, increasing and user-defined programmable load to evaluate scratch hardness and scratch adhesion of coatings.
