ZHN Nanoindenter

The ZHN nanoindenter (Zwick/Roell) is used for comprehensive mechanical characterization of thin layers, materials and tissues. With its 2 N force unit it allows quick determination of mechanical properties of (small) bones and soft tissues, such as hardness or Young’s modulus at a resolution ≤ 0.02 µN (force measurement) and ≤ 0.002 nm (displacement measurement).
