Ultra Nanoindentation Tester (UNHT³)

The ultimate high-resolution, high-stability nanoindenter

The UNHT³ ultra-high resolution nanoindenter with real force sensors is used to examine the mechanical properties of a material at the nanoscale. The UNHT³ virtually eliminates the effect of thermal drift and compliance due to its unique and patented active surface referencing system. Therefore, it is perfectly suited for long-term measurements on all types of materials, including polymers, very thin layers, and soft tissues.

Key Features

The best metrological nanoindenter for measurements at low forces

  • Real force sensors on the top reference ensure direct measurements of forces on the microNewton level
  • Active top referencing: unique patented design (EP 1828744 and US 7,685,868)
  • From low penetration depths (a few nm) to high penetration depths (up to 100 μm)
  • From low loads (10 μN) to higher loads (up to 100 mN)

The nanoindenter with the highest stability on the market

  • Long-term creep tests require no thermal drift correction
  • Uncorrected thermal drift down to 10 fm/sec, leading to elimination of thermal drift
  • High frame stiffness (>108 N/m) even at high loads
  • Unique Macor materials which have no thermal expansion
  • Full feedback control of load and depth

"Quick Matrix" indentation mode with “Script” mode

  • Fast matrix of measurements with the “Quick Matrix” indentation mode: up to 600 measurements per hour compliant to ISO14577 instrumented indentation testing (IIT)
  • The new “Script” mode allows you to create a customized template from exported data so you can be flexible and faster on analysis
  • Multi-sample holder for launching a series of tests overnight with 6 samples or more

The high-sensitivity nanoindenter for accurate surface detection

  • High-quality load-depth curves with loads <0.1 mN
  • Ultra-sensitive surface detection with stiffness detection
  • Measurement of soft gels as well as hard materials
  • Load resolution of 0.003 µN
  • Displacement resolution of 0.003 nm

Multiple modes of testing for multiple modes of analysis

  • Multiple testing modes: Continuous Multi Cycles (CMC), constant strain rate, user-defined sequences, advanced matrix
  • Dynamic mechanical analysis (DMA) mode available with the “Sinus” mode
  • Different analyses for various mechanical properties: Hardness, elastic modulus, storage and loss moduli, creep, stress-strain, Hertz analysis
  • Environmental control: vacuum, liquid, temperature, and relative humidity
